- Biological Approach
- Evolutionary Influences
- Theory of Natural Selection
- Darwin
- Enhances an individual's chance of survival and reproduction
- Genes passed down to the next generation
- Environment of Evolutionary Adaptiveness (EEA)
- Ancestral environment to which a species is adapted
- Theory of Natural Selection
- Localisation of Brain Function
- Four Lobes
- Frontal
- Thinking, creativity and personality
- Parietal
- Receive seonsory information like temperature, touch and pain
- Temporal
- Memory and auditory information processing
- Occipital
- Visual processing and receive information directly from the eyes
- Frontal
- Localisation of Language
- Broca's area
- Posterior portion of the frontal lobe
- Broca's area
- Four Lobes
- Neurotransmitters
- Chemical messengers
- One neuron communicates with another neuron at a synapse
- Synaptic cleft or gap is 20nm wide
- Released from presynaptic vesicles in a neuron
- Mental Health
- Serotonin (plays a role in mood, sleep and appatite)
- Too little causes depression
- 2022 UCL discovers this is false
- Antidepressants increase availability of serotonin at the postsynaptic receptor
- Too little causes depression
- Dopamin (allows feelings of pleasure, satisfaction and motivation)
- High levels associated with Schizophrenia
- Serotonin (plays a role in mood, sleep and appatite)
- Evolutionary Influences
