Average z-scored firing rates as a function of the Hamming distance between the preferred phonetic composition of the neuron (that producing largest change in activity) and all other phonetic combinations. Here, a Hamming distance of 0
Firing rateSingle unit recordingRatIntroduction: Although formalin-induced activity in primary afferent fibers and spinal dorsal horn is well described, the midbrain neural basis underlying each phase of behavior in the formalin test has not been yet clarified. The present study was designed to ...
leading to greater food intake, body weight and fat mass in mouse models. Blocking AMPK activity in mice led to reduced hunger and AgRP neuron firing, even after fasting. The research team found that AMPK alters the ability of AgRP neurons to form synapses, or new connections ...
Second, in the brain, there exists an abundance of top–down signals such as dopamine, acetylcholine, and neural firing13 related to the error-related negativity, that inform local populations of neurons about behavioral results. Furthermore, dopamine signals14,15 have been found to be specific ...
, Firing rate during nest entry. j, Spiking rate when virgin entered nest after shepherding (red) or voluntarily (grey). Data are mean ± s.e.m.; *P < 0.05, **P < 0.01. Full size image We investigated the interactions that activate virgin PVN and OT-PVN cells. We ...
In this chapter we shall study the mechanisms underlying the firing patterns of medium spiny neurons of the striatum, of inferior olivary neurons, of Purkinje cells of the cerebellar cortex, and of thalamic and subthalamic neurons. 展开
This ex vivo operation allows researchers to study the preserved brain for several hours, providing enough time to map the various projections that the ROI communicates with and the manner that it speaks (cell firing rate, ratio of receptors). These practices are the stepping-stones towards ...

摘要: The types of spike trains recorded in real neurons from different parts of the brain, can either be completely random or bursty. Certainly, at very high firing rates regular spike trains are observed.DOI: 10.1007/3-540-59497-3_179 被引量: 3 ...
it is estimated that approximately 70% of bladderafferent neuronsin the rat are of the C-fiber type. These neurons exhibit high threshold tetrodotoxin-resistant sodium channels and action potentials and phasic firing (one to two spikes) in response to prolonged depolarizing current pulses. Approximate...
