    Does anyone have mouse brain atlas by Paxinos and Franklin (2001)?

    Dear Saskia i would very much appreciate if you can send me PDF form of atlas and yes i need it for mouse brain but we work with rats also so it whont be for nothing :)

    Thank you Beatrice for your effort but i dont have funds to buy the book at the moment. 

  • Mona Ellaithi asked a question:
    Is there anyone who has experience with CinnaPure DNA extraction kits?

    I would like to use these kits to extract DNA from blood and paraffin waxed tissue.

    Does anybody know of any electrogenic abilities in fossil fish?
    So, as many of you are probably aware, there are several living groups of fish which are able to use electroreception to some degree to either passively sense the world around them or, in some cases, actually stun or kill other animals. In particular, I'm thinking of members of the Gymnotiformes (including the electric eel), the electric catfish (Malapteruridae), the torpedo rays (Torpediniformes) and several families of the Osteoglossiformes (Mormyridae and Gymnarchidae).

    I was wondering if anyone knew of any evidence that a now totally-extinct group of fish may have possessed similar electroreceptive/generative abilities (that is to actually generate electric fields, rather than sense them as in sharks or paddlefish). I know that in South American knifefish (Gymnotiformes), the development of an electricity-generating system has strongly constrained the development of their locomotion, which makes me wonder whether a similar morphology among extinct fish (say, xenacanth sharks) might be indicative of such behavior.

    I vaguely remember that I heard some theories about Galeaspida or Osteostraci possibly having an electrogenetic sense.
    But the only "reference" I can give you at the moment is just the page about Osteostraci on the tree of life project page:
    http://tolweb.org/Osteostraci
    I (or you) will have to dive more deeply into the literature aboput them to get some usefull, quoteable references.

    Why do penguins have double trachea?
    What is the physiological significance of double trachea? It is seen in penguins,sea lions, dugongs spoonbills petrels .
    Gerhard Forstenpointner · University of Veterinary Medicine in Vienna
    It would be surprising if penguins did not perform their phonation by means of the syrinx, the unpaired vocal organ that is situated at the bifurcation of the trachea. Therefore, the penguin's ability to "speak with two voices" is obviously limited by only one available voice-producing organ (sorry Anja!). Additionally, the term "double trachea" sounds a bit exaggerated, as it refers only to a tracheal septum which divides the tracheal lumen in its caudal part, just a few centimeters before it reaches the syrinx. The cranial and middle part of the trachea, at least three quarters of its length form a normal bird trachea with unpaired lumen. However, the presence of similar structures in other aquatic/diving species suggests a function within the complex of respiratory regulation.

    How to convert blood meal size from mg to ml?
    I have data on blood meal size in mg per flea. I need to convert it to volume. Could someone recommend me any publication about blood density in gerbils?

    Thanks, Marshall. It's free! Got it. See you in Austin.

    How old age at preputial separation onset in rat?
    What is the main sign to identify preputial separation?

    What will happen for dead sperm in hen oviduct?
    after artificial insemination?

    I think the lysis would affect DNA quality also so I don't believe it would be useful for DNA work either. Why would you want to use it?
  • Hrvoje Brzica added an answer:
    Can anyone give me any file where I can find internal anatomy and physiology of female Wistar rats?
    I'm going to help in a research and I want to learn first what it's already known. Thanks.

    http://ia700409.us.archive.org/9/items/laboratorymanual00hunt/laboratorymanual00hunt.pdf - Here is rather old e-book.

    Good account on Rat anatomy with high focus on CNS and sense organs can be found in this book if you can get your hands on it.
    Anatomy and Embriology of Labaratory Rat by Hebel and Stromberg. Sadly I think you can not find it as an e-book.
  • Zheng Hua Liang asked a question:
    How to conduct the acoustic startle experiment on the mouse?
    I want to see the neuron groups involved in the acoustic startle response in the mouse. What kind of instruments should be purchased? Is the Brainware/ Metlab software necessary?
