Chapter 4: Brain Flashcards
Hydraulic Metaphors
-The pineal gland that the soul comes in to the body; at the moment of conception dive into the body you chose your parents in this idea. Picking the right couple and coming into the pineal gland. Septic bank, gases and spirits boiling about in your brain
Mechanical and Telephone Metaphors
Wheels turning and churning in brain, keep the machine of the brain moving. Telephone: wires connect, input and out put.
Computer Metaphors
in put and process and store, recall and put out. Images tell you in our history how ideas have changed and could change in the future

Nervous System
Central Nervous System and Peripheral Nervous System
Central Nervous Sysem
Brain and Spinal Chord:
Your brain, spinal cord and nerves that connect everything, between organs and receive impulses. Conclusions get made, command gets sent out.
Peripheral Nervous System
Somatic and Autonomic( Sympathetic and parasympathetic)
Somatic: contract muscles, runs our muscles makes us move. Autonomic: regulates blood and glans etc. Work without you thinking about them ->parasympathetic: sit down, relax (couch potatoes) ->sympathetic: makes you get up, hear rate up(energy)
Motor Neurons
Lead commandments to different part of your body. -Ex: send messages to relax, 20 minutes until class ends, take a nap etc
Sensory Neurons: afferent(to brain)
detect something. Ex: heat, cold. Outside physical world. Sensitive, send that info to the brain
Interneurons
In between, connect in between.
Structure of a Neuron:
- Dendrites: receive signals and lead them to the cell. Decisions get made to what to do with that info. Example: run away from danger
- Cell Body: nucleus
- Axon: messages away from the cell
Neuron Communication
- Axon terminals release neurotransmitter
- Neurotransmitter enters into synapse.Neurotransmitter binds to receptors that it fits
Brain Stem
Brain STEM keeps you breathing, and more
- Pons (“Fay Faceandear”) networks the cerebellum with the rest of the brain
- Medulla- automatic functions breathing and heart rate
- Reticular Formation(“Downtown Dreamteam”) regulates sleep, wakefulness,arouses cortex and screens incoming info ; maintains life support
3 Parts of Brain Stem
- Pons (“Fay Faceandear”) networks the cerebellum with the rest of the brain
- Medulla- automatic functions breathing and heart rate
- Reticular Formation(“Downtown Dreamteam”) regulates sleep, wakefulness,arouses cortex and screens incoming info ; maintains life support
Cerebullum
- Regulates movement and balance
- Involved in remembering simple skills and acquired reflexes
- Plays part in analyzing sensory info, involving problems, understanding words
Thalamus
Relays sensory messages to cerebral cortex
Includes all sensory messages except from olfactory bulb
