CREB activates gene transcription in neurons that results in the formation of ________.
A) myelin sheath
B) dendritic spines
C) more receptors
D) All of the choices are correct.
CREB
A cellular transcription factor that activates gene expression in response to various stimuli, playing a key role in many cellular processes including memory formation.
Gene Transcription
The process by which the DNA sequence of a gene is copied into messenger RNA (mRNA), initiating protein synthesis.
Dendritic Spines
Protrusions on a neuron's dendrite that receive synaptic inputs from other neurons.
- Comprehend the biological foundations underlying memory and learning processes.
- Understand the importance of neural plasticity in memory formation and learning.

Final Answer :
B
Explanation :
CREB (cAMP response element-binding protein) is a cellular transcription factor that activates gene transcription in neurons, leading to the formation of dendritic spines, which are small protrusions from a neuron's dendrite that typically receive input from a single synapse of an axon. This process is crucial for synaptic plasticity and memory formation.
