However, although individuals with lived experiences desire support with monitoring and improving broader h...
Article
Background Web-based resources can support people with bipolar disorder (BD) to improve their knowledge and self-management. However, publicly available resources are heterogeneous in terms of their quality and ease of use. Characterizing digital health literacy (the skillset that enable people to navigate and make use of health information in a we...
Article
Background : Smartphone apps have potential for delivering interventions and supporting self-management in bipolar disorder (BD), however clinical trials of mental health apps have high dropout rates and low sustained use in real-world contexts. To support the development of app-based interventions, we explored use of and attitudes towards apps amo...

Article
Full-text available
Downloading a mobile health (m-health) app on your smartphone does not mean you will ever use it. Telling another person about an app does not mean you like it. Using an online intervention does not mean it has had an impact on your well-being. Yet we consistently rely on downloads, clicks, ‘likes’ and other usage and popularity metrics to measure...
Article
Full-text available
Delphi consensus consultation methods and community-based participatory research (CBPR) are distinct approaches that have traditionally been employed separately. This paper explores the integration of Delphi methods with CBPR in a research project that sought to identify effective self-management strategies for bipolar disorder (BD). We introduce o...
Article
Appreciative inquiry (a research approach comprising four stages: Discovery, Dream, Design, and Destiny) was used at a research-intensive university to investigate which teaching practices positively influence student well-being (i.e., their health and quality of life). In a survey, undergraduate students were asked to select the teaching practices...
Article
Full-text available
Objective: Internet (eHealth) and smartphone-based (mHealth) approaches to self-management for bipolar disorder are increasingly common. Evidence-based self-management strategies are available for bipolar disorder and provide a useful framework for reviewing existing eHealth/mHealth programs to determine whether these strategies are supported by c...
Article
Full-text available
Rationale, aims and objectives: Current Web technologies offer bipolar disorder (BD) researchers many untapped opportunities for conducting research and for promoting knowledge exchange. In the present paper, we document our experiences with a variety of Web 2.0 technologies in the context of an international BD research network: The Collaborative...

Article
Full-text available
Bipolar disorder (BD) has been related to heightened creativity, yet core questions remain unaddressed about this association. We used qualitative methods to investigate how highly creative individuals with BD understand the role of symptoms and treatment in their creativity, and possible mechanisms underpinning this link. Twenty-two individuals se...
Article
Full-text available
Visual mentation is the experience of visual images in the mind and includes visual aspects of perception, mental imagery, mind wandering and dream-ing. We propose an Integrative Theory of visual mentation (VM) that unifies biopsychological theories perception, dreaming and mental imagery. Un-der the theory, we make three major hypotheses where VM...
Conference Paper
Full-text available
It has been suggested that creativity can be functionally segregated into two processes: spontaneous and deliberate. In this paper, we propose that the spontaneous aspect of creativity is enabled by the same neural simulation mechanisms that have been implicated in visual mentation (e.g. visual perception, mental imagery, mind-wandering and dreamin...

Translation is a multimedia dance performed on a vertical wall filed with the projected image of a lunar surface. Pendaphonics is a low-cost, versatile, and robust motion-sensing hardware-software system integrated with the rigging of Translation ...
Technical Report
Full-text available
Collaborations between artists and scientists have yielded many notable innovations. Yet, such collaborations are generally underutilized, mostly due to the myriad obstacles faced by the partners entering into such collaborations. These obstacles include financial considerations (e.g., a lack of available grant funds), social and political tensions...
Conference Paper
Full-text available
This paper describes the research work being carried out by the Transforming Pain Research Group -- the only group whose work is entirely focused on the use of immersive VR for chronic pain management. Unlike VR research for acute or short-term pain, which relies on pain "distraction," this research posits a new paradigm for the use of VR. In addit...
Article
Full-text available
The synapses formed by the mossy fiber (MF) axons of hippocampal dentate gyrus granule neurons onto CA3 pyramidal neurons exhibit an intriguing form of experience-dependent synaptic plasticity that is induced and expressed presynaptically. In contrast to most other CNS synapses, long-term potentiation (LTP) at the MF-CA3 synapse is readily induced...
Article
The research program aims to explore and examine the fine balance necessary for maintaining the interplays between technology and the immersant, including identifying qualities that contribute to creating and maintaining a sense of "presence" and "immersion" in an immersive virtual reality (IVR) experience. Building upon and extending previous work...
Conference Paper
Full-text available
Neuroscience has benefited from an explosion of new experimental techniques; many have only become feasible in the wake of improvements in computing speed and data storage. At the same time, these new computation-intensive techniques have led to a growing gulf between the data and the knowledge extracted from those data. That is, in the neuroscienc...
Article
The neural mechanisms mediating prepulse inhibition (PPI) appear to have relevance to neurological and psychiatric disorders. Patients with temporal lobe epilepsy exhibit psychotic symptoms and disrupted PPI, therefore the present experiments examined the consequences of seizures induced by kindling on PPI. Rats were chronically implanted with an e...
Article
We present a novel interactive system that uses electroencephalographic (EEG) signals obtained from the user as a primary input for navigation through an immersive real-time 3-D visualization of various regions of the human brain. This "NeuroFloat" system is delivered via a head-mounted display (HMD). Our primary goal in developing NeuroFloat was t...
Article
We found evidence that the effects of exposure to the stimulation environment on the convulsions and interictal behaviour of basolateral amygdala (BA)-kindled rats are the result of Pavlovian conditioning. In Experiment 1, the rats first received 45 BA stimuli in one environment (CS+) and 45 sham stimuli in another environment (CS-). During this fi...
Article
Full-text available
Rats received kindling stimulations to the perirhinal cortex (PRh), ventral hippocampus (VH), or dorsal hippocampus (DH) in 1 environment and an equivalent number of sham stimulations in a 2nd environment. The PRh-kindled rats displayed rapid kindling and a swift emergence of conditioned interictal defensiveness. In contrast, the VH- and DH-kindled...

Conventional kindling experiments appear ideal for generating inadvertent conditioned effects: A variety of stimuli (e.g., removal from the home cage, attachment to the stimulation lead, and placement in the stimulation environment) are repeatedly presented to the animal prior to each stimulation and convulsion. We recently demonstrated that the st...
Article
Full-text available
The present study showed that amygdala-kindled rats use short-interval timing superimposed on phase or ordinal timing to predict when a convulsion will occur. In 2 experiments, rats received 1 stimulation and 1 sham stimulation each day, always at the same times (conditioned stimulus [CS]+ and CS- times, respectively) and 150 s after rats had been...
Article
Rats received 53 stimulations to either the left basolateral amygdala (BA) or left anterior neocortex (AN) in one environment (CS+) and 53 sham stimulations (the stimulation lead was attached but no current was delivered) in another environment (CS-), quasirandomly over 54 days. Confirming a previous report [Barnes, S.J., Pinel, J.P., Francis, L.H....
Article
Rats received 30 stimulations and 30 sham stimulations (the lead was attached to the subjects but no current was delivered) to the left basolateral amygdala in a quasirandom sequence. Stimulations were preceded by the presentation of 1 flavored solution conditional stimulus (CS+); sham stimulations were preceded by the presentation of another flavo...
Article
Mild periodic electrical stimulation to any one of many brain sites leads to the development and progressive intensification of elicited motor seizures. Since its discovery in 1969, this kindling phenomenon has been widely studied both as a model of epileptogenesis and as a form of neuroplasticity, and recently there has been increasing interest in...
Article
The authors showed that conditional effects of the stimulation environment modulate both the ictal and interictal behaviors of rats subjected to amygdala kindling. Rats received 53 stimulations to the left basolateral amygdala in 1 conditional stimulus (CS) context (CS+) and 53 sham stimulations (the stimulation lead was attached but no current was...

Article
Rats with cannulae guides implanted in the rhinal cortex were tested on a delayed non-matching-to-sample task, following either lidocaine or sham microinfusions. Bilateral lidocaine microinfusions to the rhinal cortex produced significant delayed non-matching-to-sample deficits. These results are consistent with the putative role of the rhinal cort...
Article
Long-term amygdala kindling in rats results in large and reliable increases in emotional behaviour that model the interictal emotionality often observed in temporal lobe epileptics [Kalynchuk L. E. et al. (1997) Biol. Psychiat.41, 438–451; Pinel J. P. J. et al. (1977) Science197, 1088–1089]. These experiments investigated the persistence of these k...
