Summary
The nervous system
Area of Science:
- Neuroscience
- Computational Neuroscience
- Biochemistry
Background:
- The nervous system's function relies on a complex network of neurons and synaptic connections.
- Neuromodulators dynamically alter neural circuitry, forming intricate biochemical networks.
- The 'wiring diagram' alone is insufficient to understand nervous system computation.
Purpose of the Study:
- To review the operation of neuromodulatory networks.
- To discuss challenges in studying and understanding neural computation due to neuromodulation.
- To propose a framework for understanding neural computation by analyzing modulatory networks.
Main Methods:
- Review of existing literature on neuromodulation and neural computation.
- Conceptual analysis of the interplay between neuronal and biochemical networks.
- Exploration of the structural and functional logic of modulatory systems.
Main Results:
- Neuromodulatory networks are integral to nervous system computation, acting as a biochemical layer.
- Understanding neural computation requires integrating the effects of neuromodulators.
- The complexity of neuromodulation poses significant challenges for traditional experimental approaches.
Conclusions:
- The neuronal wiring diagram is insufficient for a complete understanding of nervous system computation.
- Considering the logic of modulatory networks is crucial for deciphering neural computations.
- A new conceptual framework integrating neuronal and neuromodulatory systems is needed.

Neuronal Communication
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...
Synaptic Signaling
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Synaptic Signaling
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.

Neural Circuits
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...

The Synapse
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.
Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
