Cannabinoids and the Modulation of Striatal Plasticity

Sriatal plasticityand how cannabinoids might be able to help treat it

SK channel modulation rescues striatal plasticity and control over habit in cannabinoid tolerance

Striatal plasticity can be caused by a number of factors. Some of these factors include head trauma for a brain injury, an infection or a contracted pain. Cannabinoids have been said to have the ability to treat chronic pain through their neuroprotective and anti inflammatory abilities. Cannabinoids are naturally discovered in the marijuana plant (cannabis sativa). Cannabinoids include tetrahydrocannabinol (THC) and cannabinol (CBD).

THC is the psychoactive constituent of marijuana and gives you the high sensation when ingested. CBD is the medicinal ingredient of marijuana and this gives you the feeling of being comfortable. The endogenous cannabinoid network has two cannabinoid receptors, 1 and 2, that allow cannabinoids to bind and thrive throughout the body.

This paper will look at the effectiveness of cannabinoids in the mediation of chronic nonmalignant neuropathic pain.

Main Points:

  • Endocannabinoids Regulate Neuronal Activity
  • Cannabinoid Tolerance Impairs Synaptic Plasticity

Endocannabinoids Regulate Neuronal Activity

Endocannabinoids moderate our brains neurophysiology within a part of the brain called dorso-lateral striatum (DLS). This are of the brain has a part to play in habitual actions aka our good and bad habits. How synaptic endocannabinoid transmissioning lends a hand to habitual actions are still not clear from pathological and physiological situations. Experiments on mice have been carried out in relation to their tolerance of cannabinoids. Researchers have discovered that continued triggering of the endocannabinoid route impaired endocannabinoid controlled long-term sadness and synaptic return signals in the dorso-lateral striatum (DLS).

This impairment of long-term controlled sadness within the brain was due to

The loss of eCB LTD, occurring preferentially at cortical connections to striatopallidal neurons, was associated with a shift in behavioral control from goal-directed action to habitual responding.

Cannabinoid Tolerance Impairs Synaptic Plasticity

Researchers here discovered that cannabinoid tolerance prevents normal functioning of bidirectional synaptic plasticity in the DLS and that this is related to the alteration from objective-directed to habitual achievement. Researchers discovered that the changing of the DLS mediates endocannabinoid controlled transmissioning and plasticity and the contingent balance between objective-focused and habitual actions.

As researchers looked for the DLS, desensitization and downregulation of cannabinoid 1 receptor may explain for these neurophysiological modulations. Researchers here saw that numerous THC injections, but not a single administration, prevented endocannabinoid long term sadness in the DLS, inhibited behavioral tolerance and promoted habit communication.
