New Salamander Info.

All of the below was copied from the  Subcortical Brain site which now has a new focus.

I realized that my Subcortical Brain site was attempting to serve two different purposes:  
    1) supplement Herrick's presentation of salamander neuroanatomy with information which may be relevant to salamanders' neurotransmitters and hormones; and  
    2)  provide a model of subcortical function which will hopefully shed light on human behavior. 

Although these these two goals are not mutually contradictory, they are different, and dealing with both of them on the same website was awkward.  So I've split the site into two.   
    Goal #1, "supplement(ing) Herrick's presentation of salamander neuroanatomy with information which may be relevant to salamanders' neurotransmitters and hormones" has been moved to this new "Herrick Update" site
    Goal #2, providing "
a model of subcortical function which will hopefully shed light on human behavior" will remain in  Subcortical Brain

    
Herrick's Brain of the Tiger Salamander is a marvelous piece of work, but it's outdated.  Most importantly, it does not give any consideration to neurotransmitters or the endocrine system.  So I'm going to use this site to start to update Herrick's book.  

The update is currently divided into three sections:   
    1)  Neurotransmitters in various animals, including mammals, which are associated with 12 of the
tracts identified by Herrick in tiger salamanders and which are listed in  Tract Details .   This data is used with the unsupported assumption that the neurotransmitters of the tracts have not changed during evolution. 
    2)  Neurotransmitters identified in amphioxus, lamprey and salamanders. 
    3)  Hormones identified in amphioxus, lamprey and salamanders. 


    1)  Neurotransmitters associated with 12 tracts identified in tiger salamanders

Tract Details  doesn't seem to provide much info on neurotransmitters, so I've made
a new page:
  Tract Neurotransmitters  .          


    2)  Neurotransmitters identified in amphioxus, lamprey and salamanders. 

     I'm hoping to outline the evolution of nerves and their neurotransmitters from the amphioxus through the lamprey to salamanders. 
If possible, I would like to relate specific neurotransmitters and neuromodulators to specific  Axon Groupings
 


Amphioxus Neurotransmitters 
   
Amphioxus Acetylcholine    
   
Amphioxus Dopamine     
   
Amphioxus GABA          
     Amphioxus Glutamate    
    
Amphioxus Serotonin    


Lamprey Neurotransmitters
   
Lamprey Acetylcholine    
   
Lamprey Dopamine   
   
Lamprey GABA   
   
Lamprey Glutamate   
   
Lamprey Serotonin    


Salamander Neurotransmitters    
     Salamander Acetylcholine      
     Salamander Dopamine       
     Salamander GABA       
     Salamander Glutamate       
     Salamander Serotonin       


    3)  Hormones identified in amphioxus, lamprey and salamanders. 

    I have a number of pages on hormones which, although they all need work, could still contribute new information to the
Brain of the Tiger Salamander   just as they are.  So I'm going to go ahead and provide links to them with the expectation that I'll be coming back later to improve them.      
Lamprey Neuromodulators
Lamprey Neuropeptides    

Shark Hormones     
Teleost Hormones  
    Teleost Cortisol          

Salamander Hormones      

Human Endocrinology in General
   
    Human Reproductive Endocrinology
    Human Cortisol, etc.
    Human Testosterone
    Human AVP 
   


     I would like these sites to be useful to people who are not heavily versed in neuroanatomy.  The Figures in Herrick's book use abbreviations of technical terms which may be unfamiliar to students of psychology, etc. who haven't studied much neuroanatomy.  To make these figures more understandable, I'm compiling  a  Dictionary of neuroanatomical terms and adding as much information as I can easily find in  Tract Details .  

     I found  Brain of the Tiger Salamander  difficult to use.  In particular, it wasn't easy to match up the Figure Descriptions  with the Salamander Brain Illustrations .  In the hard copy book, it's easy to flip the pages back and forth, but here the pictures and text are in entirely different sections.  So I made the numbers of the figures in Figure Descriptions  active links.
