Action Potential: Phases of Stimulation

11.7K
The action potential is a complex electrical event that occurs in excitable cells, such as neurons and muscle cells. It consists of several distinct phases, each with specific characteristics.
Resting Phase:
In this phase, the cell's membrane is at its resting potential, typically around -70 millivolts (mV) for neurons. Inside the cell, there is a higher concentration of potassium ions (K+) and a lower concentration of sodium ions (Na+). Voltage-gated sodium channels are closed, and...

Effects of Transcranial Alternating Current Stimulation on the Primary Motor Cortex by Online Combined Approach with Transcranial Magnetic Stimulation

9.6K
Transcranial Alternating Current Stimulation (tACS) allows the modulation of cortical excitability in a frequency-specific fashion. Here we show a unique approach which combines online tACS with single pulse Transcranial Magnetic Stimulation (TMS) in order to "probe" cortical excitability by means of Motor Evoked Potentials.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Physiology

Background:

  • Sarco-endoplasmic reticulum Ca-ATPase (SERCA) is the primary transporter managing calcium (Ca2+) reuptake into the sarco-endoplasmic reticulum (SR/ER).
  • SERCA's calcium-sequestering function is vital for muscle relaxation in cardiac and skeletal tissues.
  • Dysfunctional calcium handling and subsequent ER stress are implicated in neurodegenerative diseases, diabetes, and cardiovascular diseases.

Purpose of the Study:

  • To review the fundamental mechanisms of calcium ion transport by SERCA.
  • To explore the critical role of SERCA in cellular calcium homeostasis.
  • To examine the involvement of SERCA in the pathogenesis of various diseases.

Main Methods:

  • Literature review of scientific articles on SERCA function and its role in disease.
  • Analysis of studies investigating calcium handling and ER stress.
  • Synthesis of information regarding SERCA's therapeutic potential.

Main Results:

  • SERCA actively pumps calcium from the cytosol back into the SR/ER, maintaining low cytosolic calcium levels.
  • Proper SERCA function is essential for efficient muscle relaxation and preventing cellular stress.
  • SERCA dysfunction contributes to ER stress and is linked to various pathologies.

Conclusions:

  • SERCA plays a pivotal role in maintaining cellular calcium balance and preventing ER stress.
  • SERCA's involvement in disease pathogenesis highlights its potential as a therapeutic target.
  • Further research into SERCA function could lead to novel treatments for calcium-related disorders.
