Exam 3- behavioral neuro study guide

What is behavioral neuroscience

Exploration of the brain pathways that leads to diff behaviors 

• What behaviors are studied?

• Generally common behaviors within and often between species 

• Have an evolutionary history 

• Have a genetic basis may be modified by experience 

• Often called “modified behaviors” or instincts 

How do you explore behavior?

• Objective descriptions of behavior 

• Study the anatomy of the brain’s pathways 

• Study the neuros-chemicals that are used in these pathways (including hormones)

• How these pathways develop (including genetics) and evolve

Gonads

Create Gametes

what are gametes?

create sex cells

SRYG

sex determining region

stages of development

Zygote stage-> early fetal development->middle fetal development->puberty  -> late adulthood

XY

creates testes determining factor

when do testes turn on

Early to mid fetal stage

masculation of the brain

Testes-> T->DHT-> masculation of the body (penis and scrotum)

masculation of the brain

testes-> T->E(estrogen)-> masculation of the brain (not sure if this occurs in humans)

Androgen receptors

responsible for DHT production

Intromidding

Cartosispp go in rat vajayjay

Keratosis

rat back arch

Lordosis reflex

Mechanical energy on the back that causes the rat to arch if she wants to fuck 

TDF

testes defining factor

SRY

sex determining region

Zygote

determining whether to be an xx or xy

Early fetal fetal

development of testes or ovaries

Middle

hormones ,dht, t and e (organization of the brain)

Puberty for females

• Ovaries turn on

• E and P cycles 

• Menstrual cycles

• Ovulation

• Feminization of the body

• brain?

puberty for males

• Testes turn on 

• T 

• Spermatogenesis

• Masculinization of the body.

• brain?

Late adulthood for women

• Ovaries turn off

• E & P turning off

• Menopause

• Lack of interest in sex 

• Masc hair growth (huh)

• Pain during sex

Late adulthood for men

• Testes slow down

• T lvls go down

• Very little t is needed to want sex
