Continuing yesterday‘s discussion on signal transduction. What do we mean by a signal? Signal in what form is transferred? What is this electrical and chemical signal? The cell has resting membrane potential -70 mV when we touch a hot object there is an influx of positive ions inside the cell. Changing the membrane potential from -70 mV to +30mV or even 0 mV that’s how electrical Signal is generated inside the cell The influx of ions or exchange of ions. Can we measure this signal?can be really find out how much time does it take for the signal to travel from one neuron to the other?What is special about neurons then other cells?

The oscilloscope can be used to measure these signals?? Do we really need to insert the electrode inside the neurons and outside the cell Measure potential difference?

Can we compare the Phyllanthus plant and humans for the sleep-wake cycle? The sleep-wake cycle is regulated by the nervous system? Does light have any role to play in the sleep-wake cycle? The internal clock of the sleep-wake cycle can work in the absence of light?

Celebration of goof ups!!! The question was to find out if light has any role to play in the sleep-wake cycle. The experiment was conducted by Laxmi Putting five Phyllanthus plant in continuous light! With no control!redesigning that same experiment

Introducing mango mapping To Cubist from Goa

Can we make instruments to measure if the sleep-wake pattern of Phyllanthus plant having a cut-off point The angle of the leaf to the stem? when it is sleeping and when it is awake We need to standardise it just like titration having a cut-off point when can we say that the Phyllanthus plant is sleeping

@karnamdpdurga @Farhan @drishtantmkawale
@Lydia @yash_sheregare please add on to the summary and ask some leading questions for further discussion

Snails Learning and Memory

Achatina fullica

What is habituation :thinking::thinking:

Habituation is the process in which there is a decrease in response to a stimulus after repeated intervals.

Short term objective: to habituate snails to stop reacting to touches given to tentacles

Long term objective: to re-sensitize snail to contract it’s tentacles

Procedure :
When you touch The tentacle of the snail with cotton bud for the first time both the tentacles contract

After touching them for the fifth time only the tentacle that has had contact with the cotton bud contracts the other tentacle that wasn’t touched doesn’t contract

After the 10th touch the tentacle that was touched doesn’t contract.

For re-sensitising

After habituating the snail we gently shake or poke the snail so that the snail feels like it is in danger and then the snail starts contracting it’s tentacles again.
