Document Summary
Mental processes: memory, problem solving, reasoning, language. Biological perspective: structures of brain and central nervous system. Study inherited tendencies, dispositions, and behaviours such as: Studies social and cultural influences on human behaviour. Stresses importance of understanding those influences when we interpret behaviour of others biology and behaviour. Neurons: are related to all of our thoughts, feelings, and behaviours. A neuron is a specialized cell that conducts impulses throughout the nervous system. Help make the brain more efficient by: Performing other manufacturing, nourishing, and clean-up tasks. Neurotransmitter: junction where axon of sending neuron communicated with receiving neuron across synaptic cleft. White, fatty coating wrapping around some axons. Acts as insulation and enables impulses to travel much faster. Chemical released into synaptic cleft from axon terminal of sending neuron. Crosses synapses and binds to appropriate receptors on dendrite or cell body of. Inside of neuron has a slight negative electrical charge compared to outside. Positively charged particles flow into the cell.
