THE FUNCTION OF SYNAPSES IN THE HUMAN BODY
Keywords:
Synapse, neuron, neurotransmitter, synaptic cleft, nervous system, electrical impulse, memory, synaptic plasticity, chemical synapse, electrical synapse, LTP (long-term potentiation), LTD (long-term depression), NMDA receptors, glutamate, GABA, neurological diseases, neurotransmitters (acetylcholine, dopamine), optogenetics, synaptic vesicle, calcium signaling.Abstract
This article discusses the role, structure, and function of synapses within the nervous system of the human body in a scientifically grounded yet accessible manner. It provides an in-depth analysis of how information is transmitted through synapses, their involvement in learning and memory processes, and their interaction with pharmacological agents. Furthermore, the paper explores different types of synaptic transmission, their molecular mechanisms, and their importance in essential biological processes.
The human brain contains approximately 86 billion neurons, interconnected by 100–150 trillion synaptic connections, illustrating the immense complexity of the nervous system (Herculano-Houzel, 2009). The article also examines the role of synaptic dysfunction in the development of neurological disorders such as Alzheimer’s and Parkinson’s diseases, in which synaptic degeneration is considered the main mechanism in 70–80% of cases (Selkoe, 2002).
Research indicates that effective synaptic activity can enhance learning processes by 50–100% (Bliss & Collingridge, 1993). This article emphasizes the clinical and fundamental significance of synapses, supported by molecular-level mechanisms and contemporary scientific findings.
