TL;DR
Ibotenic acid injections into the nucleus basalis (Ch4) resulted in a near-total loss of cortical cholinesterase fibers, which is irreversible for at least 6 months and has no transsynaptic effect upon the number of cortical somatostatinergic, cholinergic and cholineceptive neurons.
Abstract
Ibotenic acid injections into the nucleus basalis (Ch4) resulted in a near-total loss of cortical cholinesterase fibers. This loss of cholinergic input is irreversible for at least 6 months. The degeneration of cholinergic input has no transsynaptic effect upon the number of cortical somatostatinergic, cholinergic and cholinesterase-positive (cholinoceptive) neurons.
