What is biopsychology?
Biopsychology is the study of how biological processes influence behaviors, thoughts, and emotions.
True or False: Biopsychology is only concerned with the brain.
False
Fill in the blank: The _____ system is a key focus of biopsychology.
nervous
What are the two main divisions of the nervous system?
Central nervous system (CNS) and peripheral nervous system (PNS)
What is the primary function of neurons?
To transmit information throughout the body.
Multiple Choice: Which part of the neuron receives signals from other neurons? A) Axon B) Dendrites C) Soma D) Myelin
B) Dendrites
What is neurotransmission?
The process of communication between neurons through neurotransmitters.
True or False: Neurotransmitters can only have excitatory effects.
False
What is the role of serotonin in the brain?
Serotonin regulates mood, sleep, and appetite.
Multiple Choice: Which technique is commonly used to visualize brain activity? A) MRI B) EEG C) CT scan D) All of the above
D) All of the above
What is the function of the limbic system?
The limbic system is involved in emotion, memory, and motivation.
Fill in the blank: The _____ is the part of the brain responsible for higher cognitive functions.
cerebral cortex
What is the difference between the sympathetic and parasympathetic nervous systems?
The sympathetic nervous system prepares the body for fight or flight, while the parasympathetic nervous system promotes rest and digestion.
True or False: Hormones play no role in biopsychology.
False
What is the function of the hypothalamus?
The hypothalamus regulates homeostasis, including temperature, hunger, and thirst.
Multiple Choice: Which method is used to study the effects of brain lesions? A) fMRI B) TMS C) Case studies D) All of the above
C) Case studies
What does the term ‘plasticity’ refer to in the brain?
Plasticity refers to the brain’s ability to change and adapt as a result of experience.
Fill in the blank: The _____ lobe is primarily responsible for processing visual information.
occipital
What is the role of dopamine in the brain?
Dopamine is involved in reward, motivation, and motor control.
True or False: The brain is fully developed at birth.
False
What is the function of the amygdala?
The amygdala is involved in processing emotions, especially fear and pleasure.
Multiple Choice: Which neurotransmitter is primarily associated with mood regulation? A) Acetylcholine B) Norepinephrine C) Serotonin D) GABA
C) Serotonin
What does the term ‘neurogenesis’ mean?
Neurogenesis is the process of generating new neurons in the brain.
Fill in the blank: The _____ is a structure that connects the left and right hemispheres of the brain.
corpus callosum
What is the primary role of the frontal lobe?
The frontal lobe is responsible for reasoning, planning, problem-solving, and controlling behavior.
True or False: Biopsychology only examines genetic influences on behavior.
False
What is the significance of the blood-brain barrier?
The blood-brain barrier protects the brain from harmful substances in the bloodstream.
Multiple Choice: Which technique uses magnetic fields to stimulate nerve cells? A) MRI B) TMS C) PET D) EEG
B) TMS
What is the primary function of the cerebellum?
The cerebellum coordinates voluntary movements and balance.
Fill in the blank: The _____ nervous system controls involuntary bodily functions.
autonomic
What is the role of the prefrontal cortex?
The prefrontal cortex is involved in complex behaviors, decision-making, and social interactions.
True or False: All neurotransmitters have the same function.
False
What is the purpose of a reflex arc?
A reflex arc allows for quick responses to stimuli without involving the brain.
Multiple Choice: What is the primary function of GABA? A) Excitation B) Inhibition C) Memory D) Mood regulation
B) Inhibition
What is the role of the thalamus?
The thalamus acts as a relay station for sensory information to the cerebral cortex.
Fill in the blank: The _____ regulates the sleep-wake cycle.
pineal gland
What does the term ‘biological psychology’ refer to?
Biological psychology is synonymous with biopsychology and focuses on the relationship between biology and behavior.
True or False: The environment has no impact on biological processes.
False
What is the function of the occipital lobe?
The occipital lobe processes visual information.
Multiple Choice: Which brain imaging technique measures metabolic activity? A) fMRI B) CT scan C) EEG D) TMS
A) fMRI
What is the role of the basal ganglia?
The basal ganglia are involved in the control of movement and coordination.
Fill in the blank: The _____ is the outer layer of the brain.
cerebral cortex
What is the primary focus of neuropsychology?
Neuropsychology focuses on how brain function relates to behavior and cognitive processes.
True or False: The spinal cord is part of the peripheral nervous system.
False
What is the significance of the hippocampus?
The hippocampus is crucial for memory formation and spatial navigation.
