Document Summary
Sensation: the process of receiving, converting and transmitting raw sensory information from the brain, we need perception to make sense by selecting, organizing and interpreting sensory info. Human sensory processes: vision, the brain decodes this info by o firing rate of neuron o type of neuron o physical location of neuron, physical stimulation of receptor brain interpretation conscious sensory experience o visual cortex in the occipital. Thresholds in sensation lobe: audition o auditory cortex in the temporal lobe, olfaction o temporal lobe and the limbic system, gustation, absolute threshold: minimum amount of a stimulus that an observer can reliably detect, difference threshold: minimal difference needed to notice a stimulus change; also called the. Reducing sensory information o limbic sysmte, frontal lobe: sensory reduction, body senses o motor cortex in the frontal lobe and the parietal lobe, somatosenses o tactile sense (touch) o filtering and analyzing incoming sensations before sending a neural message to the cortex (reticular formation is responsible)
