hyperexcitation
Abnormally heightened activation
Hyperexcitation describes a state of excessive stimulation or arousal, whether in neurons, bodily systems, or psychological states.
In neuroscience and medicine, it refers to cells or tissues that have become abnormally responsive or overactive, often leading to conditions like seizures or anxiety disorders.
The term extends to general contexts describing heightened emotional or mental states beyond normal levels.
The caffeine caused a kind of hyperexcitation that made it impossible to sleep.
