rootlike structures attacted to cell body that RECIEVE impulses
part of the neurostransmitter that TRANSMITS impulses
impulse that provides the basis for conduction
loose neurotransies sucked up into the axon terminal from the synaptic gap
- consists of:
- axon terminal
- gap in between the two
involved in behavioral patterns that involve depression and anxiety
- causes muscle contraction
- and involved in memory formation
- connected with onset of alzheimers disease
***Botlin—poison that blocks AcH release causing
inhibitory neurotransmitter that may lessen anxiety
- plays role in:
- emotional response
- linked to Parkinsons (low levels of dopamine=tremors)
- schizophrenia=overutalize dopamine
inhibit pain by locking pain-causing chemicals out of the receptor sites (aspirin of the neurotransmitters)
accelerates heart rate, affects eating, linked to activity levels and learning
imbalances linked with mood disorders like depression and bipolar
hormone that does pretty much the same thing as norepinephrine
- retrieves memories (damage to hippocampus causes victim to be only able to retrieve old memories--not create new ones. 50 first date brains)
- emotional responses
- part of the limbic system
- rage response
- source of prejudice?
relay station for senory information. sends info to the cerebral cortex (part of the cerebrum where all the higher level thinking takes place)
connects the hemispheres of the cerebrum
- wrinkled surface of the cerebrum. where all that matter junk is.
- sensations and responses
- divided into frontal, parietal, temporal,occipital lobes
gland that secretes prolactin and antideurectic hormone
- prefrontal cortex
- executive center
- home of the motor cortex
- where we make plans and decisions
- taps into any sensory to manipulate and make use of
- secretes hormones that stimulate pituatary gland
- basic drives--sex, hunger, agression
- Awareness of my true identical self, what you
- look like is on the right
- superior in visual-spacial functions
- recognition, discrimination, emotioanl response, more literal
- Perception Skills
- Language (left brain)
- Sense of Self (left brain)
- self awareness and consciousness
regulates heart rate, blood pressure, respiration autononomic nervous functions
controls tongue muscle, throat and other facial muscles that are used in speech
inability to speak fluintly. Language understood but hard to speak
traces amount of glucose metabolized in the brain to create a picture
uses changes in blood flow to make an image (more blood=more activity)
semantic processing (language stuff)
focuses on transmission of trits that five rise to behavior
natural selection and adaptation connect with behavior and mental processes transmission of traits.
split brain surgery
- -Vogel and bogen speculated that split brain surgery would help with epileptic seizures.
- -Michael Gazzaniga, did early work with the spilt brain surgery on kitties and monkeys
excites the reception site--mimics the neurotransmitter. easier to recieve neurotransmitters on the site
inhibits reception site from recieving neurotransmitters by occupying the receiving site, hence blocking the neurotransmitter from chillin there
- -“difference among people”
- -How much of your traits are influenced by heredity?
- -Only individual differences.
- protects the nerves
- Multiple sclerosis--Attack the myelin sheath
Adrenaline and nonadrenal
- adrenal glands
- Fight or flight
Differentthan neurotransmitters since hormones are secreted by glands and neurotransmitters are in the neuron. Can be either a hormone or a neurotransmitter.
