Medical imaging NEW YORK, March 6, 2024 /PRNewswire/ -- It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. A research duo at Columbia's Zuckerman Institute has found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.
Key Points:
- We showed that something similar may be happening in groups of fish that sense their environment using electrical pulses.
- Scientists have long known that electric fish sense changes in the electric fields they project into their waterscapes, much like the acoustic signals that bats and dolphins deploy.
- The fish rely on specialized organs in their skin that emit and sense electric fields to communicate.
- They analyzed whether individual electric fish were better at detecting objects by tapping into signals emitted by nearby fish.

Courtship display But the same cannot be said for a sex pheromone named for him, called darcin.
Key Points:
- But the same cannot be said for a sex pheromone named for him, called darcin.
- These findings, published today in Nature, illustrate the power of a single protein to change the brain and drive behavior.
- Darcin is one such pheromone, discovered in 2010 by Robert Beynon, PhD , and Jane Hurst, PhD , and their team at the University of Liverpool .
- Dr. Hurst and her colleagues found that male mice release darcin in their urine to mark their territory and to initiate courtship displays.

Nervous system "Your response, and that of your family, will be the same: You will stop, freeze and then move to safety.
Key Points:
- "Your response, and that of your family, will be the same: You will stop, freeze and then move to safety.
- With this study, we show in flies that a rapid release of the chemical serotonin in their nervous system drives that initial freeze.
- But previous research on flies and vertebrates has shown it can also affect the speed of an animal's movement.
- Their initial results revealed that activating neurons that produce serotonin in the VNC slows flies down, while silencing those same neurons speeds flies up.

NEW YORK, Sept. 27, 2019 /PRNewswire/ --The Columbia team behind the revolutionary 3D SCAPE microscope announces today a new version of this high-speed imaging technology.
Key Points:
- NEW YORK, Sept. 27, 2019 /PRNewswire/ --The Columbia team behind the revolutionary 3D SCAPE microscope announces today a new version of this high-speed imaging technology.
- These improvements to SCAPE, published today in Nature Methods, promise to impact fields as wide ranging as genetics, cardiology and neuroscience.
- Dr. Hillman is also working with Leica Microsystems, who have licensed SCAPE and are currently developing a commercial version of the system.
- These methods let scientists see structures and connections deep inside intact samples, from whole mouse brains to tumors and human biopsies.
In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain maintain these kinds of long-term memories.
Key Points:
- In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain maintain these kinds of long-term memories.
- With today's study, we've shed new light on the molecular underpinnings behind our brain's ability to make, keep and recall memories over the course of our lives."
- All memories, even fleeting ones, are made when tiny branches, called axons, which extend out from neurons, connect to each other.
- They found that CPEB3 is present at the brain's synapses when memories are formed and recalled.
The results of this study, published today in Nature Neuroscience, illustrate the extraordinary flexibility of the growing brain.
Key Points:
- The results of this study, published today in Nature Neuroscience, illustrate the extraordinary flexibility of the growing brain.
- Woolley, PhD , a principal investigator at Columbia University's Mortimer B. Zuckerman Mind Brain Behavior Institute and the paper's senior author.
- But the trills, peeps and warbles sung by the more than 5,000 species of songbirds come close.
- The researchers examined brain cells called neurons that comprise the auditory cortex, the brain region that listens to sound.
Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work together to help the body sense where it is in space.
Key Points:
- Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work together to help the body sense where it is in space.
- To accomplish this feat, the researchers harnessed SCAPE, a cutting-edge microscope developed at Columbia that images neurons at lightning-fast speeds.
- By creating 3D, live action images of nerve cells in larvae as the animals crawled, SCAPE allowed the researchers to see exactly how those cells along the body wall reported movements back to the brain.
- "Working together, we quickly found that we could record nerve cells flashing inside fruit fly larvae as they crawled.

The new research, published today in Cell Reports , provides evidence that learning and memory are not relegated to a few select regions, but instead may permeate the brain.
Key Points:
- The new research, published today in Cell Reports , provides evidence that learning and memory are not relegated to a few select regions, but instead may permeate the brain.
- Most cells are made up of a cell body, but neurons have a more complicated shape; they have branches jutting outward from their body.
- These treelike branches, called dendrites, can extend from a single cell by the thousands, linking and sending electrical pulses to dendrites from neighboring neurons.
- "The result is an intricate network of dendrites filling the somatosensory cortex's top layer, like the canopy of a dense forest."

This brain area, called CA2, is part of the hippocampus, a larger brain structure known to be critical for our memory of people, places, things and events.
Key Points:
- This brain area, called CA2, is part of the hippocampus, a larger brain structure known to be critical for our memory of people, places, things and events.
- CA2 was already known to specialize in social memory, the ability to remember encounters with others.
- Surprisingly, today's findings reveal that a single brain region can control both higher-order cognition, like social memory, and an innate, instinctual behavior like social aggression.
- This provided striking evidence that social memory deficits, a key feature of schizophrenia, may have their origins in CA2.
