Neuroscience and Beyond
We are young researchers at the forefront of neuroscience in Göttingen, Germany, driven by a passion for discovery and communication. In our monthly conversations, we go beyond publications to discuss the real stories with leading experts: their revolutionary work, their personal paths, the struggles they've overcome, and the big questions driving the field forward.
Our mission is built on a simple, powerful idea: knowledge is the only resource that grows when shared. Through open dialogue, we aim to build a bridge between cutting-edge research and the curious minds eager to understand it.

How Our Brains Process Numbers | Prof. Andreas Nieder
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Walk into a room and you instantly know, roughly, how many people are there, without counting. So does a monkey. So does a crow. So, strangely enough, does a bee!
In this episode, Andreas Nieder - Professor of Animal Physiology at the University of Tübingen and one of the world's leading voices in cognitive #neuroscience - takes us inside the brain circuits that let humans and animals alike sense "how many."
Nieder has spent his career recording single neurons in crows, macaques, and human patients through rare clinical collaborations to understand the brain's #NumberSense. He discovered neurons in the prefrontal and parietal cortex that respond most strongly to a preferred number, regardless of how it is presented. Studying these "number neurons" reveals how the brain supports memory, abstraction, and complex thought.
In the episode we talked about:
- Why mathematical #prodigies rely on memory rather than a different "math brain"
- How the concept of zero became one of humanity's greatest intellectual discoveries
- Why birds and mammals independently evolved similar number-processing #brain networks
- What #dyscalculia is and why it affects approximately 5% of the population
- How brain injuries can impair numerical cognition and mathematical abilities
This is a conversation for anyone curious about #cognition, #mathematics, animal intelligence, or what it really means for a network of neurons to "understand" an abstract idea.
