  2. Neuromorphology - Wikipedia

    en.wikipedia.org/wiki/Neuromorphology

    Neurons can be found in different shapes and sizes and can be classified based upon their morphology. The Italian scientist Camillo Golgi grouped neurons into type I and type II cells. Golgi type I neurons have long axons that can move signals over long distances, such as in Purkinje cells , whereas Golgi type II neurons generally have shorter ...

  3. Neural pathway - Wikipedia

    en.wikipedia.org/wiki/Neural_pathway

    In neuroanatomy, a neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable neurotransmission (the sending of a signal from one region of the nervous system to another). Neurons are connected by a single axon, or by a bundle of axons known as a nerve tract, or ...

  4. Neural correlates of consciousness - Wikipedia

    en.wikipedia.org/wiki/Neural_correlates_of...

    Neurons with such properties were less frequently observed in the primary visual cortex that corresponds to relatively early stages of visual processing. Another set of experiments using binocular rivalry in humans showed that certain layers of the cortex can be excluded as candidates of the neural correlate of consciousness.

  5. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap. Neurons are the main components of nervous tissue in all animals except sponges and placozoans.

  6. Neuronal tuning - Wikipedia

    en.wikipedia.org/wiki/Neuronal_tuning

    In the olfactory system, neurons may be tuned to certain kinds of smells. [9] In the gustatory system, different neurons may respond selectively to different components of food: sweet, sour, salty, and bitter. [9] In the somatosensory system, neurons may be selectively tuned to different types of pressure, temperature, bodily position, and pain ...

  7. Excitatory synapse - Wikipedia

    en.wikipedia.org/wiki/Excitatory_synapse

    Neurons form networks through which nerve impulses travels, each neuron often making numerous connections with other cells of neurons. These electrical signals may be excitatory or inhibitory, and, if the total of excitatory influences exceeds that of the inhibitory influences, the neuron will generate a new action potential at its axon hillock ...

  8. Ventral tegmental area - Wikipedia

    en.wikipedia.org/wiki/Ventral_tegmental_area

    The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.

  9. Nigrostriatal pathway - Wikipedia

    en.wikipedia.org/wiki/Nigrostriatal_pathway

    The substantia nigra is located in the ventral midbrain of each hemisphere. It has two distinct parts, the pars compacta (SNc) and the pars reticulata (SNr). The pars compacta contains dopaminergic neurons from the A9 cell group that forms the nigrostriatal pathway that, by supplying dopamine to the striatum, relays information to the basal ganglia.
