Crow Brain Outpaces Humans and Monkeys

Researchers at the University of Tübingen discovered that crows produce visual decisions twice as rapidly as humans and monkeys.

Key points

• Microsoft's New AI Diagnoses Diseases Up to 4 Times More Accurately Than Doctors.
• Philipp Schmidbauer and Professor Andreas Nieder from the University of Tübingen's Institute of Neurobiology indicated that this quick decision-making is visible in the activity of crow brain neurons.
• "Even when the patterns of motion were hard to recognise, the crows' decisions were still better than random choices, " Schmidbauer remarked.
• "These findings show that neuronal dynamics in the avian brain are consistent with established models of decision-making in humans and nonhuman primates, " Nieder remarked.
• Neural activity gradually rose as the decision was being formed, until it reached a decision threshold and the crow indicated its choice.

Philipp Schmidbauer and Professor Andreas Nieder from the University of Tübingen's Institute of Neurobiology indicated that this quick decision-making is visible in the activity of crow brain neurons. Their study appeared in the journal Science.

In the experiment, the crows had to decide if moving dots on a touchscreen were mostly going left or right, showing their choice by pecking at a target on the same side as the dots.

"Even when the patterns of motion were hard to recognise, the crows' decisions were still better than random choices, " Schmidbauer remarked. "And with clear signals, they achieved an accuracy of nearly 100%."

To study this skill, the researchers measured neuron activity in the nidopallium caudolaterale, an significant part of the crow brain similar to the human prefrontal cortex. Just 70 milliseconds after the visual cue began, the neurons began to show different signals for each motion direction, well before the crows responded.

Neural activity gradually rose as the decision was being formed, until it reached a decision threshold and the crow indicated its choice. The neurons reflected both the strength of the available visual information and the direction selected. Eco-Friendly Paper Straws May Actually Be Worse for Environment Than Plastic.

Although birds lack a layered cerebral cortex, their differently organised brains appear to implement comparable basic principles of decision-making, and do so twice as fast as primates. Nieder remarked this speed may stem from birds' evolutionary need for rapid visual processing and motor responses during flight and foraging. Stay Connected with ProPakistani.
