NEURONS & SYNAPSES
NEURONS
PROCESS & TRANSMIT
SIGNALS
Vary in size and shape
3 STRUCTURES
Dentrites
(fibres)
Receive signals
Cell body
Axon
(output)
Carries signal to
cells
Connections btw
dentrites and axon
=
SYNAPSES
Neurons respond
to these inputs
Send pulse to
other neurons
= Information
processing
1st few
years life
Develop rapidly
Guided by genes
and environement
Synapses proliferate
and strengthen
THrough life
=
PLASTICITY
ADULT LIFE
Average neuron
Connected to
10,000 - 20,000
other neurons
Networks speed
increases
= myelination
DEVELOPEMENT
Governed by
feedback
Networks frequently used
Strenghten
Networks
not used
Disappear
Process info
more effectively
SYNAPSES (junction)
Action potential
(elec pulse from cell body)
Axon
Release
neurotransmitter
(chemical)
Cross gap
Attach to
receptor
Electrical event
(excitation)
New neuron produces
Action potential
Info btw neurons travels
diff frequency
Amount info increases
decreases
