The Peripheral Nervous System
Sensory nerve receptors allow you to interpret the world through:
- Thermoreceptors
- Photoreceptors
- Chemoreceptors
- Mechanoreceptors
- Nocireceptors
Describe the frontal lobe
Performs higher cognitive functions. Long term memories are stored here. Allows us to be aware of the self. Also contains:
- Brocas area – for language & speech
- Motor cortex – motor action
Describe the Parietal lobe
Responsible for visual attention & touch perception. It allows us to integrate senses, to conceptualize key features of the world around us. It also contains:
- Somatosensory cortex – for detecting touch/pain sensations
- Dorsal stream of the visual system
Describe the Occipital lobe?
This area is responsible for vision. And contains the visual cortex. Visual information is received from the retinae and processed here.
Describe the Cerebellum
This area is responsible for fine motor control. Balance and fine movements are processed here. Reflex memory is also stored here.
Describe the Brainstem
This area is responsible the low level autonomic system: heart rate, swallowing reflex, blood pressure, digestion, temperature, sweating and levels of alertness. It provides the link to the spinal cord.
Describe the Temporal lobe
Responsible for auditory perception, speech memory & learning. It also contains:
- Ventral stream of the visual cortex – What pathway
- Auditory cortex - for processing sound
- Wernicke region – for speech
- Hippocampus – for memory formation
What are the 6 senses of primates
hearing, sight, smell, taste, vestibular, somatosensory
