A potential consequence is that bursts will enhance the response to the immediate sensory event over responses to less urgent, modulatory inputs. (jneurosci.org)

Sensory neurons take information from your senses (what you see, touch, taste, etc.) to your brain. (clevelandclinic.org)
Here we use single-nucleus RNA sequencing to profile RNA expression in 188,776 individual interneurons across homologous brain regions from three primates (human, macaque and marmoset), a rodent (mouse) and a weasel (ferret). (nature.com)
Neurons in the brain. (bookriff.com)
Importantly, whereas the anterior brain of an adult Drosophila contains about 100,000 neurons (Zheng et al. (springer.com)
At least part of the answer, Ramón y Cajal hypothesized, lay in a specific class of neuron-one found in a dazzling variety of shapes and patterns of connectivity, and present in higher proportions in the human brain than in the brains of other species. (harvard.edu)
Now, in a study published in the March 22 issue of Nature , researchers from Harvard Medical School, New York Genome Center, New York University and the Broad Institute of MIT and Harvard have detailed for the first time how interneurons emerge and diversify in the brain. (harvard.edu)
These results together suggest that sensory cortices are capable of adapting to intense experiences by going through a recalibration of corresponding or neighboring sensory area(s) to redirect the sensory function and exhibit remarkable extent of neuroplasticity within the brain. (intechopen.com)
The brain interprets these sensory cues to understand what's going on outside and inside the body. (healthline.com)
carry sensory information to the brain. (flashcardmachine.com)
The cortex is made up of interconnected networks containing many different classes of neurons, whose roles in both normal brain activity and disease are poorly understood. (yale.edu)
One of the most fundamental elements of brain function is a reciprocal interaction between excitatory and inhibitory neurons. (yale.edu)
Overall, the brain consists of networks of neurons that send electric pulses to one another. (micropsychology.org)
Different groups of those firing neurons represent concepts that the brain uses in the evaluation process. (micropsychology.org)
Using brain slices from mouse somatosensory thalamus and cortex, we achieved the first dual recordings of directly connected thalamic and cortical neurons and compared between cortical responses to single thalamic spikes and to bursts. (jneurosci.org)
The experiments also showed that each circuit receives both long-range input from the brain and local sensory feedback. (elifesciences.org)

Are Sensory Neurons in the Cortex Committed to Original Trigger Features? (intechopen.com)
Direct connections from the contralateral cortex and the ipsilateral side activate NDNF + neurons, which subsequently inhibit the late spiking activity of underlying layer 2/3 neurons, but not layer 5. (biorxiv.org)
The precise pattern of connections between a local group of neurons in the cortex gives rises to its elementary unit of computation - the cortical microcircuit. (berkeley.edu)

The descending neurons thus constitute a bottleneck for information conveyed to motor command centers. (springer.com)

Alpha a motor neurons of which stimulation of a single nerve fibre excites from 3 to 2000 skeletal muscle fibres which we call the motor unit. (positivehealth.com)
But a small number of large sensory fibres from the muscle spindles terminate directly on the anterior motor neurons. (positivehealth.com)
Second, a group of neurons, called motor-neurons, have axons that connect to muscle units and to glands. (micropsychology.org)
Firing in the motor neurons activates their muscle units and the glands. (micropsychology.org)
Each firing motor neuron represents its activated muscle unit, and their entire pattern represents the turning of the head. (micropsychology.org)
Throughout the animal kingdom, from insects to mammals, animals possess specialized circuits of neurons that are responsible for producing these patterns of muscle contraction. (elifesciences.org)

Fig. 3: Cortical LHX6 + LAMP5 + interneurons are much more numerous in primates and are molecularly similar to conserved hippocampal interneurons. (nature.com)
A hippocampal interneuron. (harvard.edu)
