Chpt. 4 Flashcards
Neurons
Nerve Cells transmit info
Early Physical Growth
- lose weight in 1st week
- will gain 6+ lbs and 4 in 3 months
- 5-7oz weekly
Synapses
Gap between axons and dendrites of communicating
Synaptogenesis
Synapse Formation
Myelin
Sheath around axons that speed up transmission from neuron to neuron
Myelination
Myelin developing over neurons, over an axon
Exuberant Synaptogenesis
Produces far mor synapses than required in experiences!
Synaptic Pruning
Use it or lose it; synapses die off if unused
Experience expectant
Anticipate experiences; brain waiting o synapse experiences ex. language
Experience Dependent
Learn from experiences; synapses not expecting in advance and “learn”
Sensory Capabilities
From birth babies can hear, see-ish, taste, smell
-Can see change in position, temperature, pressure
Reflexes
