TIME Perception of Surabhi Gupta

It is not the river that flows but the water. Not the years that go by, but ourselves. - Hevré Bazin

Transcending Death!

205 days in an underground cave In 1972, under observation of NASA scientists, Michael Siffre went underground (literally). ‘ What happens if nothing happens?’ He spent most time sitting in the dark

In 1972, under observation of NASA scientists, Michael Siffre went underground (literally).

‘ What happens if nothing happens?’

He spent most time sitting in the dark

The counter in our psyche In his ‘mind’, time had slowed down Reports indicate: His day lasted for 24.5 hours 16 were spent awake

In his ‘mind’, time had slowed down

Reports indicate:

His day lasted for 24.5 hours

16 were spent awake

Suprachiasmic nucleus (SN) ‘ above’ [optic] ‘chiasma’ in the hypothalamus Circadian Clock Synchronizes to cues called zitetegabers. Neural path is the Retinohypothalamic Tract

Where did it go? Time is motion Psychological time is derived from intervals between events Muscle synchronization by basal ganglia In Japanese Tea ceremony every detail of tea-making is prolonged & becomes an event in itself.

Time is relative "Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity." - Einstein

Tick-Tock genes Experiment with Euglena Four genes activate and deactivate in a 24-hr cycle Cell division and metabolism also coordinated with the circadian pacemaker.

Biological time Pineal gland controls sleep and waking rhythms It releases the hormone, melatonin to regulate cycles at the tissue level Neurotransmitters like beta-endorphin and serotonin influence perception of time

Pineal gland controls sleep and waking rhythms

It releases the hormone, melatonin to regulate cycles at the tissue level

Neurotransmitters like beta-endorphin and serotonin influence perception of time

The Dracula hormone Melatonin production: Inhibited by light Stimulated by darkness Triggers seasonal breeding in animals In humans, helps set the biological clock A small dose of melatonin Given in morning : delays the clock Given in afternoon/evening : advances the clock

Melatonin production:

Inhibited by light

Stimulated by darkness

Triggers seasonal breeding in animals

In humans, helps set the biological clock

A small dose of melatonin

Given in morning : delays the clock

Given in afternoon/evening : advances the clock

(En)lightening knee Biological rhythm markers: Body core temperature Rise in melatonin Light shown on the back of knee advanced biological clock by up to 3 hours

Biological rhythm markers:

Body core temperature

Rise in melatonin

Light shown on the back of knee advanced biological clock by up to 3 hours
