BRAIN CHANGES IN ADOLESCENC.E wahooo freaking wahooo; speciifc changes

Front

prefrontal cortex: higher order cognition; limbic system: amygdala and our frekaing emotions; hypothalmaus: endocrine system ; corpus callosum is still developing which makes it easier to learn languages when young

Back

what are molecular genetis?

Front

molecular and structure/function of genes

Back

what are learned behavioral traits?

Front

Back

positive feedback / estrogen in girls

Front

ovaries send estrogen --> hypothalamus; hypothalamus sends GnRH --> anterior pituitary; anterior pituitary sends LH --> ovary --> more estrogen

Back

a

Front

Back

what are the four permanent reflexes?

Front

breathign, eyeblinking, pupils, swallowing

Back

aa

Front

Back

what is complex behavior?

Front

insect can fly man. It can frekaing fly!!!!!!!

Back

negative feedback / progesterone in girls

Front

too much LH, ovary sends progesterone --> hypothalamus

Back

what is heritability technical/y

Front

the % of variation of traits that is due to genes

Back

nature vs nurture

Front

Back

global changes in the brian in puberty?

Front

increase in myelination and increase in synaptic pruning- focus on connections we are using most. **what we do during our teenage years is actually V important because that's what will be reinforced and last and stay pruned.

adolescence man. ADOLESCENCE.

Front

what are innate behaviors

Front

Back

if you have four twins raised in barrels, the heritability is what?

Front

0.99

Back

what is behavior?

Front

ethology - observe those animals man. Observe them!!!!!!!

Back

what is the central dogma of molecular genetics?

Front

gene -> rna -> amino acid -> protein -> behavior

Back

heredity

Front

Back

gross vs fine motor skills

Front

adoption studies

Front

Back

how does PKU relate to nature vs nurture?

Front

mutations to a gene that codes for a liver enzyme. Phenylalanine doesn't get converted, so too much phenylalanine can cause brain problems. If you do the right diet, it is OKAY. Interaction between genes and environment.

Back

if you have four twins raised in the rainforest, palace, egypt, and a spacestation, what is heritability?

Front

0

Back

monozygotic vs dizygotic twins

Front

monozygotic: one egg, one sperm; dizygotic: two eggs, two sperm

Back

how does methylation impact transcription?

Front

if you methylate it you kind of silence it because it's harder for transcription factors to bind

Back

what two things are associated with orientation

Front

kinesis: undirected and v random; taxis: respond to an external stimulus, a directional movement

Back

what is FAP?

Front

fap = fixed action patterns; we just do the thing. Ex. Praying mantis
