More with less: @UCSanDiego scientists in @ucsdbiosciences and @UCSDPhySci have proposed a solution for how flies use a simple but efficient method to recognize odors. The answer lies at the edges of their sensory systems. today.ucsd.edu/story/detecti… @yahdef @SuLabUCSD @PuriPalka

Detecting Odors on the Edge: Researchers Decipher How Insects Smell More with Less

While humans feature a sophisticated sense of smell, insects have a much more basic olfactory system. Yet they depend upon smell to survive. Scientists have figured out how fruit flies use a simple...

The array of olfactory receptor neurons in flies is highly structured. Our collaborator Chih-Ying Su @SuLabUCSD showed previously that receptors are electrically coupled, a coupling that affects animal behavior. nature.com/articles/nature11… 2/

Non-synaptic inhibition between grouped neurons in an olfactory circuit

Nature - It has been suggested that the electrical activity of one neuron can influence that of its unlinked neighbour, but this so-called ephaptic effect is widely assumed to be weak and has been...

Building the FlyWire #connectome from the FAFB brain was a massive team effort. But neuroscientists need to find their favourite neurons in this huge dataset. We report an indexed parts list, systematically annotating all 127k neurons (Schlegel et al biorxiv.org/content/10.1101/…) 1/7

A consensus cell type atlas from multiple connectomes reveals principles of circuit stereotypy and...

Today the lab was greeted by innocuous appearing white adapters plugged in lab bays and offices. We inquired and learned the university is monitoring 'occupancy', i.e. when we are/are not in. Be on the lookout! Big brother is watching!👀

[1/11] @DavidTadres and I are excited to share new research doi.org/10.1126/sciadv.ade72… where we show that olfactory sensory neurons undergo silencing due to depolarization block at ethologically relevant odor concentrations. #olfaction #chemosensation #behavior

Depolarization block in olfactory sensory neurons expands the dimensionality of odor encoding

Silencing olfactory sensory neurons through depolarization block shapes the peripheral representation of odors.

It is generally accepted that fat tissues “talk” to the brain via secreted hormones. Our amazing student @yuwang, co-mentored by @liye_tsri, discovered that somatosensory neurons innervating adipose tissue act as a break to counteract sympathetic activity. nature.com/articles/s41586-0…
