Self-Organization In Animal Societies

Concludes Baier: “Neurobiological findings, such as ours, can perhaps inspire and enrich the thinking about the self-organization of animal societies in general, which is currently the domain of other scientific disciplines.”

Social Attraction And Affiliation

The nerve cells identified by the researchers in this region of the thalamus connect the visual system of the zebrafish with other brain regions that are active during social behavior.

The importance of the newly identified neurons was confirmed when the researchers specifically blocked the function of these cells. Zebrafish larvae lost their interest in conspecifics as well as moving dots and hardly followed them around anymore.

The neurons we discovered thus regulate social approach and affiliation in zebrafish,” says Johannes Kappel, graduate student and lead author of the study.

Humans Possess A Thalamus, Too

“… and many neuronal processes have been conserved during evolution. We also have brain regions that are active when we perceive facial movements or body motion, but the significance of these regions for social behavior has not been explored”, continues Kappel.

The study by Kappel, Larsch, Baker and their collaborators has shed light on a part of the brain whose activation provides the elementary “glue” for the bonding of two zebrafish. Collectively, such small-scale interactions create shoals of fish. Social behavior is driven by networks of brains, which are themselves networks of neurons.

The Brain’s Thalamus

“The thalamus is a sensory control center of the brain that integrates and relays sensory inputs,” explains Johannes Larsch. Sensory information is processed on its route to the thalamus, first in the retina and then in the tectum, a major visual center of the vertebrate brain.

By the time the information arrives in the thalamus, it has already been filtered for social cues, such as the jerky movements of a potential conspecific.

Visual Stimulus For Shoaling Behavior

Johannes Larsch’s team nevertheless found a way to elucidate the importance of the visual system in social interactions. The scientists developed an experimental virtual reality setup for zebrafish larvae that simulates conspecifics. All that was needed was a projected dot on a screen, which – and this is important – moved across the display with a jerky movement pattern that is stereotypical of swimming zebrafish.

Actions And Reactions, Senders And Receivers

There’s an inbuilt challenge in studying social interactions: For us as observers, actions and reactions are intermingled, both in animal behavior and at the neuronal level,” explains Johannes Larsch, neurobiologist and project leader in Herwig Baier’s department at the Max Planck Institute of Neurobiology.

This is because individuals taking part in these interactions influence each other. Both are, at the same time, senders and receivers of social signals. It has been particularly hard to investigate the role of the visual system and its associated brain areas.”

The Irresistible Visual Cue

The zebrafish larvae could not resist this cue: They followed it around for hours, apparently confusing the moving dot with a real conspecific. The researchers had thus discovered a defined visual stimulus that triggers shoaling behavior.

The team could now investigate the neuronal processing of the stimulus. The experiments revealed that a moving dot activates a specific set of neurons in a brain region known as the thalamus. The same area of the thalamus gets activated when another zebrafish larva swims nearby.

Looking For Teammates: Mostly Consciously

Humans are famously social animals. But they are not alone in their tendency to team up with other individuals of the same species (conspecifics) to reach their goals. In fact, herds of mammals, flocks of birds, or shoals of fish are abundantly observed in nature. How does an animal’s brain recognize other animals of its own kind?

“Knowing” Teammates: Mostly Unconsciously

Humans and many other animals live in societies. At a fundamental level, social interactions require individuals to identify others as belonging to their own kind. This usually happens in fractions of a second, often instinctively. Unveiling the neuronal circuits that underly this behavior, however, is anything but trivial.

“An idea is something that won’t work unless you do.” - Thomas A. Edison

A special network that runs from the eye’s retina deep into the brain may help mediate social attraction and affiliation, a new study reveals. It seems that “to see is to know”. But how would we feel about that if it partly or wholly explained our social behavior and relationships? What if we were the zebrafish of the experiment?

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
