Mind Reading and Writing: The Future of Neurotechnology. Pieter Roelfsema c.s. publish white paper in Trends of Cognitive Sciences


Advanced methods to record brain activity make it increasingly possible to access an individual’s mental processes (i.e., to ‘read their mind’). The information that is directly extracted from the brain can be used to control devices, artificial limbs, or obtain knowledge of (hidden) intentions.

Methods to stimulate the brain with electrical currents, optogenetics, and other methods are routinely used to probe causal relations in the brain and to restore dysfunctional neural circuits. These methods can also be used to ‘write to the mind’ (i.e., to feed information directly into the brain).

Neurotechnologies to read from, and write to, the brain might be combined in a single individual to create ‘augmented cognition’ with increased processing capacity and an enhanced cognitive repertoire. This potential methodology also raises some important ethical questions.
