false
the ________ produces hormones that stimulate the _______ to secrete releasing hormones into the circulatory system

According to René Descartes, the:
A) body influences the mind.
B) pineal body is the mind.

Rats raised in “stimulating” environments solve mazes faster than those raised in
laboratory environments. This change in behavior is most likely mediated by:
increased dendritic complexity of cortical neurons
Cortical myelination
varies by cortical region
Which of the following is a criterion for identifying a neurotransmitter?
A) The transmitter must be synthesized in the neuron or otherwise be present in it.
B) When the neuron is active, the transmitter must be released and must produce a
response in some target.

its work is done.
D) All of the above are criteria for identifying a neurotransmitter.
