Neuroscience and Consciousness Chapter 2
Neurons Neuron cell communication is electrical Axon Dendrites Mylin sheath Terminal buttons
Synapses Firing of neuron is electrical process All-or-none law Action potential Synapse communication is chemical - Excitatory Inhibitory Lock and key concept Reuptake
Neurotransmitters GABA - inhibitory Dopamine - motor activity, behavior and cognition, memory Endorphins pain reduction Serotonin stress, alcoholism,mood, suicide, aggression, sleep, sexuality Acetylcholine digestion, muscles Glutamate memory -excitatory
Cellular Biology Bruce Lipton, Ph.D. Single cells analyze S from E Cellular communities perceive E and organize = survival advantage Cooperation among groups of cells gene transfer among species Genetic engineering - dangers
Cellular Biology Environment Epigenetics genes are not destiny E can modify genes without changing their basic blueprint changes are then passed onto future generations via proteins Cells are shaped by E E signal > DNA/RNA > protein Disease cause is E, not cell
Cellular Biology Membrane Membrane has 2 parts - Receptor proteins = tuned to specific E signals physical signals; energy fields Effector proteins = appropriate life sustaining R generate motor nerves Together they create a S-R mechanism Membrane Is cell s equivalent of a brain Functions like a computer chip Is programmable by E information
Cellular Biology Nucleus Nucleus a memory disk, hard drive containing DNA programs Data entered into cell/computer via membrane receptors = cell s keyboard Result: we have ability to edit data we enter into our biocomputers we become masters of our fate, not victims of our genes. Behavior can be controlled by thot.
Nervous System Central Nervous System Peripheral Nervous System -Somatic division -Autonomic division Sympathetic system Parasympathetic system
Endocrine System Hormones - chemical messengers Adrenal glands - - Epinephrine - Norepinephrine Pituitary gland - Sends messages to other endocrine glands to release hormones when signaled by Hypothalamus (master gland)
The Brain Major scanning techniques Older brain structures- Brainstem-medulla, pons Reticular formation Thalamus Cerebellum Limbic system Cerebral cortex - lobes
Regenerative powers Neuroplasticity Experience sculpts brain Neuroflexibility Flexibility of brain Neuroscaffolding Connections strengthened Neurogenesis brain mends itself by producing new neurons
Lateralization Hemisphere functions Split brain
Film - Split Brain
The Mind - Siegel,M.D. Mind - Develops at interface of neurophysiological processes and interpersonal relationships Experience- Leads to firing of neurons which turns on genes which produces proteins Genes - Act as templates for information that is to be passes onto next generation Have a transcription function which determines which proteins will be synthesized
Matter and Energy Lipton Matter made up of energy=spinning atoms Energetic signaling more efficient relaying E information than physical signals Every material structure radiates a unique energy signal
Matter and Energy Lipton Universe is one indivisible, dynamic whole an integration of interdependent energy fields Flow of information in a quantum universe is holistic
Matter and Energy Lipton Redundant signaling pathways Iatrogenic illness Use of energy to heal brain Communication Thoughts consume energy - negative thinking drains energy
Brain Fingerprinting Dr. Farwell s research Subject wired with EEG Views screen - names, pictures Brain R with a murmur Tested FBI agents
