The K+ Channel, A New Hope For a Better Understanding

K + channel, a new understanding of better hope that our neuronal axon is the communication pathway that exists in our nervous system. This transmission takes the form of an electrical signal, also known as action potential. Action potentials are caused by voltage changes on the axon membrane. Changes in voltage are achieved by changes in ion concentration Na +, Ca +, K + (1). At the beginning of the cell, a large amount of potassium ion K + is present in the cell and a large amount of sodium ion Na + is present outside the cell.

As Na + enters the cells and the cells depolarize, release is facilitated. When inhibitory neurotransmitters affect cells, the net result is that the K + and / or Cl - channels open. Of course, if the K + channel is open, K + will leave the battery due to the overwhelming power of electrostatic force. The role of Cl - in IPSP is more complicated and interesting, but if the membrane is stationary, Cl - does not do anything because it is balanced as above. However, if a slight excitement / depolarization message is received while the Cl channel is open, Cl - seems like an administrator or security guard and is ready to offset this claim.

Neurons are covered with semipermeable membranes containing ion channels. These ion channels switch on and off, allowing positive ions (such as sodium (Na +), potassium (K +)) and negative ions (such as chlorine (Cl -)) to enter the neurons. When neurons do not transmit information or rest, ion channels are turned off. Using a device called an oscilloscope, the neuroscientist discovered that the resting potential of neurons (or the charge of resting neurons) is -70 millivolts (mV). Therefore, an excavator with 8,400 neurons can generate up to 588 V.

When the K + channel is opened in almost the same way as Na + ion reaction, neurons are suppressed. Since the concentration of K + in the cell is higher than the outside, potassium leaves the cell when the channel is opened. Unlike Na + ions, K + ions leaving the cell produce higher negative charges in the cell. When hyperpolarization occurs, membrane potential starts to become increasingly disadvantageous. The cells are unstable until active transport occurs again and allow K + to begin repolarizing the inside of the cell. ATP again supplies the energy necessary to deliver these ions to the cell
