Cognitive Abstraction Manifolds

Cognitive Abstraction Manifolds

few days ago I started thinking about abstractions whilst reading Surfaces and Essences, a recent book by Douglas Hofstadter and Emmanuel Sander. I suspect efforts like Surfaces and Essences, which traverse vast and twisted terrains across cognitive science, are probably underrated as scientific contributions. But first, let me briefly introduce the idea-triggering tome. Surfaces and Essences focuses on the role of a...

People Like Us: How Our Brains View Others

At the most fundamental level of biology, we recognize the innate advantage of defining differences in species. But even within species, is there something in our neural circuits that leads us to find comfort in those like us and unease with those who may differ?

Aging Brains Aren’t Necessarily Declining Brains

Aging Brains Aren’t Necessarily Declining Brains

For years, conventional wisdom held that growing older tends to be bad news for brains. Past behavioral data largely pointed to loss in cognitive – that is, thinking – abilities with age, including poorer memory and greater distractibility. Physical measures of brain structure also showed atrophy, or loss of volume, in many regions with age.

What Happens in the Hippocampus?

What Happens in the Hippocampus?

This year’s Nobel Prize in medicine recognises work on “cells that constitute a positioning system in the brain.” Those cells are found in the hippocampus. It is just one tiny part of the brain, but this structure gets at least its fair share of research attention.

Review: The Transhuman Identity Thesis

A quick little short video that I recently found. This video explains a bit about transhumanism and the nature of personhood, and it's short and a good introduction for an impatient friend.

The Sensorium: A Multimodal Neurofeedback Environment

The Sensorium: A Multimodal Neurofeedback Environment

The Sensorium is a neurofeedback environment that allows people to experience signals from their non-perceptible body processes visually and auditorily. Various (neuro-)physiological rhythms and frequencies are projected simultaneously as soundscapes and “lightscapes” into the environment. A wireless physiological amplifier device sends signals such as EEG and ECG to a computer for real-time processing using the modi...
