Quiz with Complete Verified Solutions 2025
1: What is the primary function of the prefrontal cortex in cognition? -
correct answer -
The prefrontal cortex is primarily responsible for executive functions, such
as decision-making, planning, problem-solving, and regulating social
behavior.
2: How do neurons communicate with each other? - correct answer -
Neurons communicate with each other through synapses, where
neurotransmitters are released from the axon terminal of one neuron and
bind to receptors on the dendrite of another neuron.
3: What role does the hippocampus play in memory? - correct answer -
The hippocampus is crucial for the formation, organization, and retrieval of
memories, particularly long-term declarative memories.
,4: Which part of the brain is most involved in visual perception? - correct
answer -
The occipital lobe, specifically the primary visual cortex (V1), is most
involved in processing visual information.
5: What is neuroplasticity? - correct answer -
Neuroplasticity is the brains ability to reorganize itself by forming new
neural connections throughout life, allowing for learning and adaptation.
6: How does the amygdala influence emotional responses? - correct answer -
The amygdala plays a key role in processing emotions, particularly fear and
pleasure, and it helps to form emotional memories.
7: What is the function of the basal ganglia in motor control? - correct
answer -
The basal ganglia are involved in regulating voluntary motor movements,
procedural learning, and routine behaviors or habits.
, 8: What is the difference between rods and cones in the retina? - correct
answer -
Rods are photoreceptor cells in the retina sensitive to low light levels and
are crucial for night vision, while cones are responsible for color vision and
function best in bright light.
9: How does long-term potentiation (LTP) relate to learning and memory? -
correct answer -
LTP is a long-lasting enhancement in signal transmission between two
neurons that results from their synchronous stimulation, and it is
considered a major cellular mechanism underlying learning and memory.
10: What is the role of the thalamus in sensory perception? - correct answer
-
The thalamus acts as a relay station, processing and transmitting sensory
information from the sensory organs to the appropriate cortical areas for
further processing.
11: Which neurotransmitter is most commonly associated with reward and
pleasure? - correct answer -
