Abstract

How do neurons orchestrate behaviour? Let us trace our footsteps back to one of the first hypotheses proposing an alliance between the brain and behaviour. This article trace Donald Hebb's life, and how, in the neurophysiology milieu of the 20th century, he revolutionized the way psychologists and neuroscientists viewed the brain, bringing a unifying concept of the mind with his publication ofThe Organization of Behaviour. In closing, the legacy of Hebb in the after-years of the monograph is discussed in the context of contemporary discoveries in the realm of neural plasticity and learning that revisit Hebbian concepts.

Hebbian theory

Hebbian theory is a neuropsychological theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell. It is an attempt to explain synaptic plasticity, the adaptation of brain neurons during the learning process. It was introduced by Donald Hebb in his 1949 book The Organization of Behavior. The theory is also called Hebb's rule, Hebb's postulate, and cell assembly theory.

Behavior

Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.

Long-term potentiation

In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. The opposite of LTP is long-term depression, which produces a long-lasting decrease in synaptic strength. It is one of several phenomena underlying synaptic plasticity, the ability of chemical synapses to change their strength.
