Biological Basis of Behavior
How might damage to Broca's area impact a person's communication skills?
Increased reading comprehension abilities due better word recognition
Enhanced auditory perception leading improved listening skills
Improved writing proficiency due enhanced grammar usage
Difficulty speaking while understanding language remains intact
If a drug functions as an antagonist for dopamine receptors, what is its likely effect on neuronal communication?
It enhances dopamine reuptake efficiency thereby reducing synaptic transmission intensity.
It mimics dopamine's effects by activating neurons more effectively than natural neurotransmitters can do so themselves.
It increases dopamine production leading to heightened activation of neural pathways associated with reward and pleasure.
It will block dopamine from activating neurons by occupying its receptors without triggering them.
What neurotransmitter imbalance is most consistently implicated across different studies involving patients with schizophrenia?
Serotonin deficits are commonly found across all cases of schizophrenia regardless of symptom type or severity.
Acetylcholine levels tend to show abnormalities that directly correlate with cognitive dysfunction in schizophrenia patients.
An excess of dopamine activity is often associated with schizophrenia symptoms.
Glutamate hypoactivity has been proposed as being responsible for all subtypes of schizophrenia uniformly across individuals afflicted by it.
What is the synapse?
The pathway for electrical signals in the neuron
The junction where two neurons meet
The gap between the axon of one neuron and the dendrites of another
The location where neurotransmitters are stored
What process immediately follows neurotransmitter release into the synaptic gap?
The neurotransmitter molecules bind to receptor sites on the post-synaptic neuron’s membrane.
The pre-synaptic neuron reabsorbs excess neurotransmitters through reuptake.
Sodium-potassium pumps restore resting potential after an action potential.
Voltage-gated ion channels in the axon hillock open in response to stimulus.
Why would myelin sheath degeneration impact conduction speed along an axon?
Maintenance of resting membrane potential
Formation of cytoskeletal transport structures
Regulation of neurotransmitter synthesis
Leading to saltatory conduction
When a neuron is at rest, what is typically true about its electrical charge relative to its outside environment?
The inside and outside have no electrical charge difference.
The inside has a negative charge compared to outside.
The charges continually reverse at rest.
The inside has a positive charge compared to outside.
