Unit 8- Neuropsychology Flashcards
These neurons send messages from the central nervous system to the muscles of the body
Motor Neurons
This part of the brain receives sensory input for touch and body position
Parietal Lobe
This type of brain scan watches blood flow and oxygen consumption in the brain
fMRI
This is a random change in our genes that could lead to a change in our genotype or phenotype
Mutation
This part of the brain is involved in controlling our heartbeat and breathing without our conscious awareness
Medulla
The ability to process multiple things at different levels of consciousness is referred to as:
Dual Processing
This is the space between neural connections where neurotransmitters travel to meet receptors:
Synapse
This part of the neuron is where the genetic information is found
Nucleus
When a part of our brain is communicating and processing information with another part right next to it, it’s called:
Anatomical Connectivity
Our ______ is the manifested traits of an organism
Phenotype
The study of environmental influences on gene expression that occur without a DNA change
(activates and deactivates certain traits in the DNA gene)
Epigenetics
Evolutionary Psychology
The study of the evolution of behavior and the mind using principles of natural selection
The study of the relative power and limits of genetics and. environmental influences on behavior
Behavior Genetics
Parallel Processing
Processing many aspects of a problem simultaneously
-Doing 2 things at once
Sequential Processing
Processing one aspect of a problem at a time
-Taking your full focus onto one thing at a time
Our brains ability to create new connections despite an injury or our age
Neuroplasicity
Reticular Formation
Nerve network that travels through the brain stem into the thalamus.
-Helps control arousal
The brains sensory control center
-Sends information from the brain stem to the cortex and cerebellum
Thalamus
Helps in processing sensory input coordinating movement and balance and implicit memory
Cerebellum
Amygdala
Influences our motivational/emotional control/fear response to interpretations of nonverbal continual expressions
Endocrine System
The body’s “slow” chemical communication system consisting of a set of glands that secretes hormones into the bloodstream
Dopamine
- Influences movement and learning
- Attention/Emotion
- Excess is linked to schizophrenia
- Too little is linked to Parkinson’s
Neurotransmitter
- Mood, hunger, sleep, arousal
- Too little is linked to depression
Serotonin
The sending neuron absorbs back any neurotransmitters left in the synapse
Re-uptake
Brain Lesion
Tissue destruction, naturally or experimentally, which can cause disruption in the brain functioning and communication
Examples of Brain Lesions
- Lobotomy
- Phineas Gage (railway spike)
- HM (hippocampus removed)
What scan shows a visual display of brain activity detecting where a radioactive form of glucose goes when the brain does a specific task
PET
Difference between hormone and a neurotransmitter
a hormone is in glands that tell what cells what to do throughout the body
a neurotransmitter works specifically in neurons
