Cell type-specific calcium imaging of central sensitization in mouse dorsal horn
www.nature.com/articles/s41...
Allodynia is a state in which pain is elicited by innocuous stimuli, for example in response to cutaneous capsaicin application. This phenomenon is mediated by spinal cord

Cell type-specific calcium imaging of central sensitization in mouse dorsal horn - Nature Communications
Altered mechanosensation by application of capsaicin to the skin is thought to be spinally mediated. Here, the authors use Ca2+ imaging in spinal neurons and develop a cell profiling approach to identify populations involved in central sensitization.

Diverse firing properties and Ab-, Ad-, and C-afferent inputs of small local circuit neurons in spinal lamina I
pubmed.ncbi.nlm.nih.gov/26797505/
More than 90% of neurons in lamina I are interneurons with unknown circuitry. In this article these neurons (47) were examined using various techniques /1
Diverse firing properties and Aβ-, Aδ-, and C-afferent inputs of small local circuit neurons in spinal lamina I - PubMed
Spinal lamina I is a key element of the pain processing system, which integrates primary afferent input and relays it to supraspinal areas. More than 90% of neurons in this layer are local circuit neu...

Neuronal circuitry for pain processing in the dorsal horn
www.nature.com/articles/nrn...
Dorsal horn receives both noxious and non-noxious stimuli from different body parts. These stimuli are further processed by interneurons and transmitted to the brain by projection neurons. /1
Neuronal circuitry for pain processing in the dorsal horn - Nature Reviews Neuroscience
Neurons in the dorsal horn of the spinal cord process sensory information and transmit it to the brain. Andrew Todd describes the complex neuronal organization and circuitry of this region and discuss...

Kappa Opioid Receptor Distribution and Function in Primary Afferents
pubmed.ncbi.nlm.nih.gov/30236284/
It`s known that KORs (kappa opioid receptors) are expressed in primary afferents. In this study it is shown that KORs are expressed in peptidergic sensory neurons and in low-threshold/1
Kappa Opioid Receptor Distribution and Function in Primary Afferents - PubMed
Primary afferents are known to be inhibited by kappa opioid receptor (KOR) signaling. However, the specific types of somatosensory neurons that express KOR remain unclear. Here, using a newly develope...

In this article 4 fluorescent proteins (red, green, yellow, cyan) also called XFPs, were introduced to create 25 transgenic lines of mice. /1
Imaging neuronal subsets in transgenic mice expressing multiple spectral variants of GFP - PubMed
We generated transgenic mice in which red, green, yellow, or cyan fluorescent proteins (together termed XFPs) were selectively expressed in neurons. All four XFPs labeled neurons in their entirety, in...

Buzsáki's Rhythms of the Brain: Cycle 5
1. General Summary
Even without any sensory input brain supports self-generated, spontaneous order. Neural connectivity constantly generates short-lived transient oscillations. Oscillations in the mammalian brain range from from minutes to 600 Hz. /1

Only excitatory interactions (like collision in classical thermodynamics) are not viable in the brain, they would just create avalanches of excitation. To maintain "tensegrical" dynamic, there should be inhibitory forces. 1/
