First Generation (1970s-1980s) of Brain-Computer Interface (BCI)

The First Generation of BCI, spanning the 1970s to 1980s, laid the foundation for the field of brain-computer interaction. This pioneering era saw the first attempts to decode brain signals, marking the beginning of a revolutionary journey.

Early Experimentation (1970s)

1. Jacques Vidal's work on EEG-based BCIs (1973)

2. Initial experiments with invasive electrodes

3. Basic signal processing techniques

Invasive BCIs ( Late 1970s-Early 1980s)

1. Implantable electrodes in animals and humans

2. Single-neuron recordings

3. Early neural prosthetic concepts

Non-Invasive BCIs (Early 1980s)

1. Development of EEG-based BCIs

2. Introduction of electromyography (EMG)

3. First non-invasive BCI applications

Notable Research and Developments

1. Vidal's "Toward Direct Brain-Computer Communication" (1973)

2. Fetz's neural control of prosthetic devices (1970s)

3. Early BCI systems for communication and control

Key Figures and Contributions
