Summary
Neural circuits and behaviors are shaped by experience during sensitive developmental periods. Molecular changes regulate this plasticity, influencing how sensitive periods function and persist.
Area of Science:
- Neuroscience
- Developmental Biology
- Molecular Biology
Background:
- Neural connectivity and synaptic communication are modified by experience during specific developmental periods.
- These modifications, occurring during sensitive periods, often lead to lifelong changes in circuitry and behavior.
- Developmentally regulated molecules influence synaptic transmission and neuronal morphology, potentially timing heightened sensitivity to experience.
Purpose of the Study:
- To review recent findings on the mechanisms regulating sensitive period plasticity.
- To explore insights from the visual and song systems.
- To raise new questions about the factors contributing to sensitive period sensitivity.
Main Methods:
- Selective review of recent research findings.
- Focus on studies from the visual system.
- Focus on studies from the song system.
Main Results:
- Identified molecular mechanisms that regulate sensitive period plasticity.
- Highlighted the role of experience in shaping neural circuits during development.
- Provided novel insights into the timing and regulation of sensitive periods.
Conclusions:
- Experience-dependent neural plasticity during sensitive periods is crucial for development.
- Molecular factors play a key role in regulating the timing and extent of plasticity.
- Further research is needed to fully understand the mechanisms underlying sensitive period sensitivity.

01:35Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
01:18Introduction to Learning
Learning is the process of acquiring knowledge or skills through practice or experience, leading to long-lasting behavioral changes. This acquisition occurs through interaction with the environment and requires practice or experience. For instance, mastering a skill such as surfing requires considerable practice and experience, highlighting the essential role of repeated interactions with the environment in learning.

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:21The Nativist Approach
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
