- Biopsychology
- split brain
- Sperry
- 11 people - 1/2 brain, control group - whole brain
- shown pics, on left or right visual field
- found - right visual field = could say and write it, left visual field = could not say or write but could choose associating object
- Sperry
- plasticity
- ability to alter and change its function
- determines how we learn and adapt to change
- creating new neural pathways
- Maguire et al
- London taxi drivers
- more grey matter in posterior hippocampus
- increased the longer they had been a taxi driver
- more grey matter in posterior hippocampus
- London taxi drivers
- Doidge
- structural changes
- axonal sprouting
- reformation of blood vessels
- recruitment of homologous areas
- structural changes
- localisation
- Broca's area
- frontal lobe
- production of speech
- Wernicke's area
- understanding language
- Temporal lobe
- visual cortex
- processes info from eyes
- occipital lobe
- auditory cortex
- temporal lobe
- processes info from ears
- somatosensory cortex
- processes info of touch, pain, temperature,
- parietal lobe
- motor cortex
- voluntary movement
- frontal lobe
- Phineas Gaga
- Broca's area
- ways of studying the brain
- fMRI
- measures increase blood flow when activity is performed
- shows localisation of function e.g. diagnose seizures / stroke
- EEG
- measures how electrical activity varies over time using electrodes
- detect and measure seizures
- ERP
- small voltage changes in brain measured by eegs + triggered by events
- gage damage
- Post-mortem
- brains from dead
- research
- fMRI
- nervous system
- synaptic transmission
- 1. action potential reaches end of neuron
- 2. neurotransmitters released from vesicle into synaptic cleft
- 3. neurotransmitters diffuse across post-synaptic membrane + bind to specific receptors
- 4. muscles contracts or hormone is secreted as a result
- neurons
- sensory
- motor
- relay
- divisions
- CNS - brain + spinal chord
- PNS
- somatic NS
- autonomic NS
- Sympathetic
- parasympathetic
- synaptic transmission
- split brain
