Synaptic refers to the junctions between neurons where communication occurs. These connections, known as synapses, play a crucial role in transmitting signals throughout the brain and nervous system.

Synonyms

intercellular, neuronal, signal-transmitting.

Examples of usage

  • The synaptic connections in the brain are vital for learning.
  • During sleep, synaptic activity increases to process memory.
  • Disruptions in synaptic function can lead to neurological disorders.

Interesting Facts

Neuroscience

  • Synapses can be chemical or electrical, with chemical synapses using neurotransmitters to send signals.
  • There are about 100 trillion synapses in the human brain, highlighting its complexity and capacity for learning.
  • Synaptic plasticity refers to how the strength of synapses changes over time, a key process in learning and memory.

Psychology

  • Changes in synaptic connections are thought to play a vital role in how memories are formed and recalled.
  • Disruptions in synaptic functioning have been linked to various mental health disorders, including depression and schizophrenia.

Technology

  • Artificial neural networks in machine learning are inspired by the way synapses operate in biological brains.
  • Research in synaptic mechanisms is paving the way for new treatments in neurodegenerative diseases like Alzheimer's.

Cultural References

  • The concept of synapses is often referenced in literature and films to illustrate the complexity of human thought.
  • Various art installations have used synaptic imagery to explore themes of connection and communication in the digital age.

Origin of 'synaptic'

Main points about word origin

  • The term comes from the Greek word 'synapsis', meaning 'junction' or 'connection'.
  • It was first used in scientific contexts in the 19th century to describe the interconnections in the nervous system.

The word 'synaptic' is derived from the Greek word 'synapsis', which means 'a joining together'. This term evolved in the context of neurobiology in the late 19th century when researchers began to identify how neurons communicate with each other. The prefix 'syn-' means 'together', while 'aptic' comes from 'apto', meaning 'to fasten or join'. The identification of synapses was essential in understanding the nervous system's functioning and laid the groundwork for modern neuroscience. Since then, the term has been used in various contexts, emphasizing the connectivity and interactions between cells in multiple biological systems.
