M current

M current is a type of noninactivating potassium current first discovered in bullfrog sympathetic ganglion cells

The M-channel is a voltage-gated K+ channel that is named after the receptor it is influenced by. The M-channel is important in raising the threshold for firing an action potential. It is unique because it is open at rest and even more likely to be open during depolarization. Furthermore, when the muscarinic acetylcholine receptor (MAChR) is activated, the channel closes. The M-channel is a PIP₂-regulated ion channel.

Actions of M-currents: "phasic-firing"

M-channels are the reason for slow depolarizations produced by ACh and LHRH in the autonomic ganglia and other specified areas. 1. Initial depolarization of a neuron increases likelihood that M-channels will open. 2. M-channels generate an outward potassium current (iK). 3. Potassium efflux counteracts sodium influx in action potential (AP). Overall result: full action potential is prevented.

Inhibition of M-current: "tonic-firing"

Plot

Sushshu [Sushanth] is a happy-go-lucky college student whose philosophy of life is summed up as Forget Yesterday, Enjoy Today & Worry Not about Tomorrow which keeps him happy but worries his parents to no end. A transfer brings the entire family to Hyderabad where he flips for his college classmate Sneha on day one. A determined Sushanth woos her successfully and we are treated to a couple of songs in the bargain. Now, Sneha's philosophy of life runs totally opposite of Sushanth and very soon reality sets in. His attitude ruins his marriage prospects with Sneha and they end up separating. The second half of the movie is all about how they try to fall out of love while making compromises to their philosophies. As expected, it ends well with both accepting that Love is above everything else in life!!!
