There are about 85 billion neurons in your brain neurophysiology and they’re sending electrical signals in your body right now! They tell your eyes to move across this page interpret the words that you read maintain your posture physiology ... all in a fraction of a second. In this section we’ll explore this vast complex system from the cellular to the sensory level.
Nervous system introduction :
neural cell types Anatomy of a neuron function Sodium-potassium pump neurons Synapse structure Neuronal synapses . neurotransmitters neurotransmitter receptors . cranial nerves spinal cord Functions of the nervous system Motor unit Peripheral somatosensation Muscle stretch reflex Choroid plexus Cerebral aqueduct Autonomic nervous system brain anatomy Cerebral cortex Schwann cells neurilemma cell
Neural cells and neurotransmitters :
Neuroplasticity Astrocytes Microglia Ependymal cells Oligodendrocytes Schwann cells
Neuron membrane potentials :
Effects of axon diameter and myelination
Sensory perception :
Visual cues Sensory adaptation Weber's law Gestalt principles
Sight (vision) :
The structure of the eye Visual sensory information Photoreceptors (rods vs cones)
Sound (Audition) :

Somatosensation :
Sensory adaptation and amplification Somatosensory homunculus Pain and temperature
Taste (gustation) and smell (olfaction) :
Olfaction - structure and function Pheromones pineal gland Gustation - structure and function
