Question
Classifying the fundamental function of dendrites in neural network Skelton?
A. receptors
B. transmitter
C. both receptor & transmitter
D. none of the mentioned
Answer
A. receptors
Explanation
Dendrites are specialized structures in neurons that primarily function as receptors. They are responsible for receiving signals from other neurons and transmitting these signals to the neuron’s cell body (soma). This process is critical for neural communication and computation within both biological and artificial neural networks.
Key Functions of Dendrites
Signal Reception:
- Dendrites receive input from other neurons via synapses, where neurotransmitters bind to receptors located on the dendritic membrane.
- This interaction generates electrical signals, which are then transmitted toward the soma for further processing.
Integration of Inputs:
- Dendrites integrate multiple incoming signals from various sources, allowing the neuron to process complex information efficiently.
- This integration can involve both linear and nonlinear processing mechanisms, enhancing computational capabilities.
Compartmentalization:
- Due to their branched structure, dendrites can compartmentalize electrical activity, enabling localized processing of inputs. This feature supports parallel computation within a single neuron.
Plasticity and Learning:
- Dendrites play a role in synaptic plasticity, which is essential for learning and memory formation. Changes in dendritic structure or receptor density can modify how signals are received and processed.
Why “Receptors” Is Correct
The term “receptors” accurately describes the fundamental role of dendrites in receiving and processing incoming signals. While dendrites can also influence downstream signaling through mechanisms like dendritic spikes or retrograde signaling, their primary function remains signal reception. The other options—transmitter or both receptor & transmitter—are less accurate because transmitting signals is primarily the role of axons, not dendrites.
In summary, dendrites act as the neuron’s primary input structures, functioning as receptors that gather and integrate information from other neurons. This makes them indispensable to both biological and artificial neural networks.
Dendrites are tree like projections whose function is only to receive impulse.
