🧠 COGNITIVE_Projects

This repository contains a collection of laboratory assignments and projects in Cognitive Neuroscience and Computational Neurobiology.
The project is organized into four main modules, each focusing on a different aspect of brain data analysis: Psychophysics, Spike Sorting, EEG, and fMRI.
