Summary
Oxytocin, a neuropeptide, modulates social behaviors by acting in the cortex. Its developmental timeline and role in cognitive processes like social recognition are key to understanding brain function.
Area of Science:
- Neuroscience
- Neuroendocrinology
- Developmental Neuroscience
Background:
- Oxytocin is a hypothalamic neuropeptide historically linked to parturition and lactation.
- Emerging research highlights oxytocin's significant role in modulating complex social behaviors.
- The oxytocinergic system's presence in the cortex is crucial for social behavior networks.
Purpose of the Study:
- To review the oxytocinergic system, focusing on cortical oxytocin release and receptor distribution.
- To examine the developmental trajectory of the cortical oxytocin system.
- To discuss oxytocin's function as a neuromodulator in cognitive processes and synaptic plasticity.
Main Methods:
- Review of existing literature on RNA, autoradiographic binding, and immunohistochemical studies.
- Analysis of developmental timelines of the cortical oxytocin system.
- Synthesis of recent findings on oxytocin's role in cognitive functions.
Main Results:
- Evidence supports oxytocin release and receptor distribution in the cortex, forming networks for social behavior.
- Developmental studies reveal the timeline of the cortical oxytocin system, influencing brain development and behavior.
- Oxytocin is implicated in sensory processing, social recognition, memory, and fear modulation.
Conclusions:
- The cortical oxytocin system is foundational for social behavior networks.
- Oxytocin acts as a neuromodulator in the young and adult cortex, influencing synaptic transmission and plasticity.
- Understanding the oxytocin system is vital for comprehending social cognition and behavior.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

01:29Excitatory and Inhibitory Effects of Neurotransmitters
13.6K
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of...

01:19Regulation of Hormone Secretion
7.0K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...
