Your brain doesnโ€™t just passively track time โณ - it structures it.
In @Science.org we show that activity in ๐Ÿง  memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2)

Cholinergic feedback for modality- and context-specific modulation of sensory representations The brainโ€™s ability to prioritize sensory information is crucial for adaptive behavior, yet its mechanisms remain unclear. We investigated basal forebrain cholinergic neurons modulating olfactory bulb...

Our new paper is out in Science.

We identified a subgroup of cholinergic neurons that mediate sensory modality-specific attention. They change their funcitonal properties within secs of behavioral context change.

Congrats to Bin for the great thesis, and the team!

Graphical abstract for "Vocal communication is seasonal in social groups of wild, free-living house mice."

The abstract has, from top to bottom, a title, four middle image panels, and two bottom text panels.

Image title: "Vocal communication in social groups of wild-free living house mice"

Middle image panels from left to right: (1) An aerial snap shot of the region where the study site is located, an agricultural landscape in rural Switzerland. (2) An image of the study site, a small barn in the forest inhabited by mice. (3) An image of a radio frequency identification (RFID) box used to track mouse social interactions. A mouse is entering the box from the left while another sits outside. (4) A spectrogram showing example vocalizations - one low frequency squeak and one ultrasonic call - recorded from an RFID box.

Bottom panels:
Left: Data Collectionย 
-ย 10 years of RFID-based tracking data (from 6,946 mice)
-ย 15 months of acoustic monitoring (totaling 6,594 hours)
-ย Machine learning for vocal detection and labeling (CNN)

Right: Key Findings
-ย Vocalization is seasonal (most in spring and summer)
-ย Vocalization is associated with the presence of pups
-ย Vocalization is correlated with social group dynamics

You have a nonlinear generative model for recorded neural data, then you again linearize it using koopman operators to design linear optimal control input. There are already ample works in the literature where you can design nonlinear energy efficient optimal controllers for nonlinear systems.

z-transform and z-score are two completely different entities. Using one in place of the other is not correct in my opinion.

Very interesting work, as a control theorist person, I think you can design a controller for a system only if it is controllable (as you have a linear system so the proof is trivial and may be added). I am also curious to know why LQR and why not Model Predictive Control?
