What effect does the release of standard hormones have on the hypothalamus and on the anterior pituitary gland?

They have an inhibiting effect. The hypothalamus and anterior pituitary gland secrete releasing and tropic hormones (respectively) which cause further cascading hormone release

Where are the receptors for catecholamines and peptide hormones located?

In the cell membranes of target cells

Where are the target receptors for thyroid and steroid hormones located?

In the cytoplasm or even nucleus of target cells (meaning they must pass through the cell membrane)

These can bind to DNA and function as transcription factors

Lipid-based hormones

These can affect NT synthesis, NT release and postsynaptic receptors (in other words, they have both fast and slow impacts on neurons)

Steroid hormones

This is the critical period of learning during which a bird listens to a "tutor" in order to learn a new song from which it develops a template for its own song

The sensory phase of vocal learning

This is the sub-song, "babbling" phase of a bird's vocal development where they must hear their own version of a learned song in order to master it

The sensorimotor phase of vocal development

This the phase of vocal learning in birds where their learned song matches the template

The crystalized phase of vocal learning

Brain structures that are sensitive to these are typically found in the hypothalamic and preoptic areas

Hormones

This prevents neuronal death in the SDN-POA of juvenile rats

Testosterone

This surpresses the development of dopaminergic neurons in male mice cells

Estrogen
