Psych brain

regions of the brain ;3

hindbrain

midbrain

forebrain

hindbrain structures ;3

-pons

-medulla

-cerebellum

midbrain structure

-reticular formation

forebrain structure ;3

-cerebrum

-thalamus

-hypothalamus

what does hindbrain do ;3

-regulation of sleep

-autonomic functions (breathing, heart rate)

-coordination of muscle movement

what does midbrain do ;3

-relays messages between hind and forebrain

-filtering/directing sensory info

-regulating arousal and alertness

what does forebrain do ;3

-mental processes

-attention and filtering sensory info

-homeostasis

What are the lobes of the brain ;4

Frontal lobe

Parietal lobe

Temporal lobe

Occipital lobe

Frontal lobe structure ;3

-prefrontal cortex

-brocas area

-primary motor cortex

parietal lobe structure

-primary somatosensory cortex

temporal lobe structure ;2

-wernicke's area

-primary auditory cortex

occipital lobe structure

-primary visual cortex

What does prefrontal cortex do

reasoning, problem solving, risk assessment

what does brocas area do

movement for speech production

what does primary motor cortex do

coordinating muscle movement

What does the primary somatosensory cortex do?

receives and processes sensory info

what does wernickes area do

comprehension and production of meaningful language

what does primary auditory cortex do

receives and processes sound info

what does primary visual cortex do

receives and processes visual info

whats brain ablation

surgical removal of brain tissue to observe behavioural changes

whats brain lesioning

damage to brain tissue on animals to observe behaviour changes, therefore different parts of brain have dif functions.

whats split brain experiments

severed corpus callosum which therefore split left and right hemisphere (cerebra hemisphere)

Acquired brain injury ;2

traumatic, damage caused externally

non-traumatic, damage by internal force

impact of acquired brain injury ;3

biological- changes to functions of organs

psychological- changes in personality, thoughts, feelings or behaviours

social- changes to interpersonal skills and interactions with others.

name parts of neuron ;8

-dendrites

-nucleus

-axon

-axon terminal

-myelin

-presynaptic neuron

-synaptic gap

-postsynaptic neuron

Damage to prefrontal cortex effects ;3

-personality change

-problem solving issues

-trouble assessing risks

damage to primary motor cortex effects

movement problems with muscles

damage to brocas area effects

brocas aphasia trouble producing movement for fluent speech

damage to somatosensory cortex and parietal lobe effects ;2

-lose sensations

-spatial awareness issues (spatial negelct)

damage to wernicke's area and temporal lobe effects ;3

-wernickes aphasia, trouble understanding and producing meaningful speech

-issues receiving sound info

-issues with facial recognition

damage to occipital lobe/primary visual cortex effects

problems detecting visual info

process of neurotrasmition ;3

1. electrical message travels from cell body down axon

2. electrical message reaches axon terminals causing neurotransmitters to be released by presynapric gap into synaptic gap

3. neurotransmitters travel across gap until detected by receptors on dendrites at post synaptic neuron

process repeats

whats neuroplasticity

brains ability to change in response to experience or environmental stimulation

process of developmental plasticity;3

-synaptogenesis

-synaptic pruning

-myelination

What is CTE

progressive fatal brain injury/disease fro repeated mild traumatic brain injury; concussions cause

whats epilepsy

neurological disorder characterised by recurrent seizures, which are brief episodes of abnormal brain activity

role of gut brain axis

connects enteric and central nervous systems, allowing brain to influence gut function and reverse.

What are the neuroimaging techniques; 4

-Computerised tomography (CT)

-Magnetic resonance imaging (MRI)

-Position emission tomography (PET)

-Functional magnetic resonance imaging (fMRI)

what types do the neuroimaging techniques do

CT=structural

MRI= structeral

PET= functional

fMRI= functional
