Resting Membrane Potential01:24

Resting Membrane Potential

18.4K
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane.
The Inside of a Neuron is More Negative
The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular fluid. The...

Resting Potential Decay

5.4K
The resting membrane potential of a neuron (-70mV) is sustained due to the selective ion permeability of the membrane. At the resting potential, the membrane is slightly permeable to ions like sodium (Na+) and chloride (Cl−) and highly permeable to potassium ions (K+). Differences in the ions' concentration inside the cell compared to the outside are maintained by membrane transport proteins like channels and pumps.
At rest, the K+ is the main ion that moves across the membrane...

Mismatch Repair

5.4K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair

Area of Science:

  • Cognitive Neuroscience
  • Neuroscience
  • Psychiatry

Background:

  • Mismatch negativity (MMN) is a key auditory event-related potential in cognitive neuroscience.
  • Reduced MMN in schizophrenia suggests potential links to impaired experience-dependent plasticity and N-methyl-d-aspartate glutamate receptors.

Purpose of the Study:

  • To review the utility of MMN in understanding schizophrenia's perceptual inference deficits.
  • To explore MMN's potential in translational research for animal models of schizophrenia phenotypes.
  • To examine MMN measurement issues, its role as a vulnerability index, and pharmacological sensitivity.

Main Methods:

  • Review of existing literature on MMN in schizophrenia.
  • Analysis of MMN measurement challenges and its use as a vulnerability index.
  • Discussion of pharmacological studies and development of animal models for MMN.

Main Results:

  • MMN is a valuable tool for investigating perceptual inference deficits in schizophrenia.
  • MMN may serve as a vulnerability marker for schizophrenia development.
  • Progress has been made in developing animal models of MMN, but challenges remain.

Conclusions:

  • MMN offers insights into the nature and time course of schizophrenia-related perceptual deficits.
  • Further research is needed to address knowledge gaps concerning MMN measurement and underlying pharmacology.
  • MMN holds promise for translational research and understanding schizophrenia pathophysiology.
