La percepción del paso del tiempo describe la experiencia subjetiva del tiempo y como un individuo interpreta la duración de un evento.
Puede variar con el estado emocional, el nivel de atención, la capacidad de memoria y con ciertas enfermedades.
Las cortezas frontal, parietal, el cerebelo, el hipocampo y los núcleos de la base están involucrados. Existen “neuronas del tiempo”.

"#Hippocampal neurons reinstate specific episodic memories in humans. These #EpisodeSpecificNeurons are independent of #ConceptNeurons or #TimeCells and code the conjunction of elements that make up the event." according to Luca D. Kolibius (1st author, https://twitter.com/LucaKolibius/status/1709953380779499696)

Ooh this seems very interesting:
Lost in time: Relocating the perception of duration outside the brain by #RobbeLab (not on here right?)
#Time #TimeEstimation #RatBehaviour #PlaceCells #TimeCells (added those last two because they seem clearly linked to the contents even though I don’t know if they’re actually discussed)I did a time-estimation experiment and yes, some of the rats did develop these kind of superstitions… like standing at the delay zone… Not all of them though, at least not that we could see! And time cells seem to tell us that they do have some internal representation of time passed… also if time is actually space does it mean that the #TemporalContexModel is actually a MovementContextModel? @marcwhoward you might be interested in this…

Time or distance: predictive coding of Hippocampal cells
We show that the type of experiment determined the cells’ encoding, such that in fixed-distance experiments distance-encoding cells dominated, while on fixed-time experiments time-encoding cells dominated.
Seems very interesting! But is it surprising? Place cells are known to encode what is consistent and disregard what is not… 🤔

@MatteoCarandini @marcwhoward thank you Matteo! Super interesting… so this would not be the same thing as hippocampal time-coding, for which the #TimeCells seem to “remap” their preferred times, right? Instead this sensory delay should be exactly the same regardless of contextual changes? And not learning-dependent?

Hi all 😃
Our latest #Review on #SplitterCells is now published in @eLife !!
I will probably write a real thread on it when I get a chance... for now:link: https://elifesciences.org/articles/82357
why: some neurons in the #Hippocampus (and other brain regions) of #Rats (and other mammals) have the fascinating ability to discriminate not just different presents, but different past or future states or trajectories in the same current situation. They could be related to #EpisodicMemory or #DecisionMaking 🤔They are called 'trajectory-dependent cells' or Splitter Cells. 🔀 We tried to make sense of them!
what: Hippocampal Splitter cells do a lot of puzzling stuff. For example there's a lot of them even in tasks that do not require the Hippocampus to be solved. They spread asymmetrically on a linear track leading to a choice point - 'past' splitters around the start and 'future' splitters towards the choice point. #TimeCells cells can be splitter cells (but they're usually #PlaceCells). Splitter cells evolve with experience, or maybe it is performance, nobody really knows. ⁉️ ... and a lot more weird stuff
conclusion: Two different computational models, the temporal context model and the latent state model, each explain a subset of the properties of splitter cells... so perhaps the Hippocampus implements both! But more experiments are needed to disentangle them 😄
now what: questions or comments? Please let us know!! ✍️

New paper possibly demonstrating time encoding for another bat... Could be my first #MastoJC (journal club) if I get some time to read it!
If you've read it: what do you think??
