Biological Behaviour Flashcards
how does aging occur
telomere degredation
what does the hypothalamus do
major regulatory centre releases tropic hormones CRF, TRH, GnRH
bridge between nervous and endocrine system
what hormones does the posterior pituitary release
ADH and oxytocin
what hormones does anterior pituitary release
FLAT PiG FSH LH ACTH TSH PROLACTIC GH
oxytocin role in psych
bonding empathy and trust
think cuddle hormone
prolactin hormone in psych
post partum depression
lactation
which hormones regulate hunger
leptin
ghrelin
neuropeptide Y
chronic stress hormone
cortisol
hormone for metabolic rate and neural development
thyroid hormone
brain imaging of function only
EEG
brain imaging of structure only
CT
MRI
brain imaging of structure and function
PET (glucose)
fMRI
difference between MRI and CT
CT exposes to X-rays but is must less costly
MRI better at imaging soft structures but more time consuming
how does PET scan work
radio labelled glucose emits positrons as it decays
when glucose decays more activity is happening in the brain
how does a functional MRI work
magnetic properties of oxygenated and deoxygenated hemoglobin to look at blood flow
cerebellum is for
coordinated movement
medulla oblongata does what
controls autonomic functions like breathing blood pressure heart rate
what does pons do
relationship station for signals
substantia nigra
neurons that communicate using dopamine to coordinate voluntary movements
ex parkinsons
inferior colliculi
auditory input
superior colliculi
visual input
limbic system is what and located where
various structures involved in emotion memory and motivation
the subcortical structures in the cerebrum
amygdala
episodic memory attention and emotion
nucleus accumbens
reward motivation and learning
implicated in addiction
