I just wanted to tell you guys that you helped me stick with my passion for neuroscience throughout my very severe depressive episode. It wasn't easy, but I never gave up. I joined a lab at my university, made friends with people in the field and I kept on learning. Now I'm finally going to start studying cognitive neuroscience (came from psychology) starting this year!

That’s fantastic to hear!

There is an episode of a mysteries show with Zachary Quinto. He jumps out of an airplane in a mask, and has to memorize images. There is a clear difference in how many he remembers vs. how many he remembers when there is no adrenaline on the ground. . Perhaps the falling experiment needs to use a mask so there is total focus on the watch, or perhaps it's just going to fast for even the stressed brain to remember.

That actually makes a lot of sense in light of the “dense memory” idea, where instead of time perception actually slowing down, the person is just forming more memories during highly emotional/intense events. Then when they look back on the memory, it seems like it took longer because they have more memories than they would typically have for that duration.

I wonder if this difference of perception of time is based on taking control of the Default Mode Network (the brain activity occurring when you aren't consciously directing your attention - daydreaming, driving long distance, etc.). Adrenaline response doesn't just affect the body readiness, it also acts as a neurotransmitter which heightens the brain attention. It triggers the fight, flight, freeze response. Whether it's a sports situation or a traffic accident, you don't really have time to think though a response in the moment. This seems to be distinctly different brain mode from DMN or consciously planned activity. As a soccer goalie, i would make instinctive saves that seemed quicker than my reaction time. When this happens, it creates a lasting slow motion memory for me.

Lana Del Rey once said: “Time present and time past Are both, perhaps, present in time future And time future contained in time past If all time is eternally present All time is unredeemable What might have been is an abstraction Remaining a perpetual possibility Only in a world of speculation What might have been and what has been Point to one end, which is always present Footfalls echo in the memory Down the passage which we did not take Towards the door we never opened Into the rose-garden”

Our many different notions of time was something that I was blessed to talk with my 1890s born great grandmother about as she knew what life was like before choo choo train standardized time or punching time clocks in factorys since she live a more rural American lifestyle. It was one where she witnessed the more subjective properties like hamiltonian oscillating waves correlated with idealized time emerge in publications. She was born on the heels of several several iterations & uses of time that took place in late 1800s early 1900s society and education.. Computation is about to take all over time anylitical task out of the majority society again. Thinking in seasons ,that meeting some one in appointment before or afternoon as markers. You no longer multi task the same rushed way as you learn in fast pace precision machining or in construction work. You have no issue envisioning how ancients built pyramid when your moving with every second monitoring ever movement made or produced.

18:16 “we live in the past “ that’s called memory , kinda like you have to go backwards to go forward. If you could better remember your dreams ( braking the vail) you would remember your future. In dreams, you can time travel. Remembering is the hard part.

Time is like the language we use to communicate, to participate in our societies on an agreed upon standard. Time varies according to situations,like if you have bills, a job, no bills and no job. Do you like what you’re doing or do you hate it or are you in love. It seems to be more of a perception and that perception is different if you’re alone or with others, misery loves company, makes time go faster. . Land time or boaters time. If you live on a boat, your time regulates more with nature, the wind, the tides and the weather. Sometimes it’s necessary to leave for shore early to meet an appointment. Our clocks whether windup or atomic have to be adjusted to meet the seasons and orbits . Our minds time clock hasn’t been figured out yet ( peer review) . They have cameras that are well beyond the 24 frames a second, that some of us use in the 60s.. then there’s dreaming or imagination. Premonition or time traveling in your mind, picturing the future. Is that skipping some time or are you just not remembering how you got there. If you’re a carpenter or architect, it’s best not to skip time on how you got to your finish project or your blueprints will suffer. I remember free falling and I was taught to pull at around 34,000 feet. After looking at my altimeter and calmly pulling my ripcord. I was told by my instructor that I was around 28,000. It’s amazing how fast you are falling. Then pop. Time. Time is a funny thing .

36:01,, your clock,, the body is only 7 years old. Within 7 years, every cell in your body has renewed, for good or bad. Epigenetics is a resent study, very interesting

Maybe kid's have more than just faster reflexes due to being physically smaller and this needs less integration time, but also live more in the present because of this.

39:47,,, the attention span of most people is the average length of a song. The length of movies are calculated with the length of frames and politics, because of short term memory, is why politicians can keep their jobs

The internal times are not the overall physical time though, these time mechanisms in the brain are comparative differentials in frequency of events over physical time. When I code I use a lot of time deltas to tie events, but all these times owe their event tracking to a more fundamental time (the computer clock). Time is a comparative between differential flow rates of motion, this is a relative reference frame of time, not the time that ties all physical transformation events.

Huh?

@NicholasWilliams-uk9xu 5 ай бұрын

@@stellarwind1946 Comparative differentials in frequency of events = time keeping in the brain. It's a product of how neurons communicate information to each other in a ensemble. (when one thing happens more than another, there is differential shifts in activity within the ensemble of neurons [the pathway being activated changes, therefore timing mechanisms have changed]).

Oh no, I got to the end of this only to hear you say something about free will that makes me question your intellectual honesty. I need to go watch your free will episode, after going through Sapolsky's book Behave and watching his "debate" with my once hero Daniel Dennett I've come to realize there is only one correct answer to this for anyone thinking deeply about what's being discussed.
