Add to dictionary

synapse

[ˈsɪnæps ]

Definitions

Context #1 | Noun

neuroscience

A synapse is the junction between two neurons, where signals are transmitted from one neuron to another. It plays a critical role in the transmission of nerve impulses, allowing for communication within the nervous system.

Synonyms

connection, interface, junction.

Examples of usage

  • The synapse facilitates the flow of information between nerve cells.
  • Dopamine release occurs at the synapse during reward signaling.
  • Changes in synapse strength are thought to underlie learning and memory.
Context #2 | Noun

biology

In a broader biological context, a synapse can refer to any junction between two cells, not just neurons. This includes synapses between immune cells or between muscle cells and nerve endings.

Synonyms

connection, junction, link.

Examples of usage

  • The immune synapse is crucial for T-cell activation.
  • Chemical signaling at the muscle synapse enables movement.
  • Synapse formation is essential for tissue regeneration.

Interesting Facts

Science

  • A synapse can be either electrical, where signals are transmitted directly, or chemical, where chemicals called neurotransmitters are released.
  • When learning something new, our brain forms more synapses, showing that engaging with information can physically change our brain's structure.
  • Some studies suggest we have approximately 100 trillion synapses in our brain, allowing for complex thoughts and coordination.

Psychology

  • Neuroplasticity, the brain's ability to change throughout life, is largely due to the strengthening or weakening of synapses.
  • Experiences, skills, and habits can be reinforced through repeated activation of specific synapses, a process known as synaptic pruning.

Pop Culture

  • In movies and literature, the concept of synapses is often used as a metaphor for connections between people, as in forming relationships.
  • Certain video games use neuroscience themes to create puzzles that require the player to think about how neural connections might function.

Literature

  • Several science fiction novels explore technological advancements that manipulate synaptic connections, blurring the lines between human and machine.
  • Writers often use the concept of synapses metaphorically to describe moments of insight or realization, as if thoughts are sparking across gaps.

Origin of 'synapse'

Main points about word origin

  • The term 'synapse' comes from the Greek word 'synapsis,' meaning 'to clasp together,' which reflects how neurons connect.
  • The word was first introduced in the late 19th century by the physiologist Sir Michael Foster.

The term 'synapse' was coined in the late 19th century, derived from the Greek word 'synapsis', which means 'connection' or 'junction.' The prefix 'syn-' means 'together' and 'haptein' means 'to fasten'. This term was introduced into the scientific community by the British physiologist Charles Sherrington in 1897, as he recognized the importance of these connections in the functioning of the nervous system. Sherrington's work on reflexes and neural pathways laid the foundation for our understanding of synaptic transmission and plasticity. Over the years, the study of synapses has evolved, leading to significant advancements in neuroscience, particularly in understanding how synaptic connections enable learning, memory, and the overall function of the brain.
