Shaken Baby Syndrome
Machine that measures the brain’s electrical activity.
Electroencephalogram
Portion of the brain farthest from the spinal cord, includes the cerebral cortex and structures beneath it.
Forebrain
Specialization of function in one hemisphere of the cerebral cortex or the other.
Lateralization
A nerve cell that handles information processing
Neurons
A layer of fat cells that helps electrical signals travel faster down the axon
Myelin Sheath
The tiny gaps between a neuron’s fibers.
Neurotransmitters
The process of encasing axons with fat cells
Myelination
A view suggesting that biological processes and environmental conditions influence the brain’s development.
Neuroconstructivist View
WHY DO WE SLEEP?
- Because sleep is necessary for survival
Evolutionary Perspective
WHY DO WE SLEEP?
- Because it cleans out waste in the neural tissue and rebuilds and replenishes the brain and body
Restorative Function
WHY DO WE SLEEP?
- Because it increases synaptic connections between neurons
Critical for Brain Plasticity
