Figure Lengend Snippet: Heat maps of median changes in coherence for δ, θ, α, and β frequency bands across lead pairs after administration of saline (NaCl), caffeine (CAF), sulpiride (SLP), haloperidol (HAL), dizocilpine (DIZ), galantamine (GAL), tropicamide (TRO), hydroxyzine (HXZ), aminophenylbutyric acid (PHB), phenazepam (PHE), atipamezole (ATI), dexmedetomidine (DEX), and 5-ethyl-5-phenyl-2,4,6(1H,3H,5H)-pyrimidinetrione (PhBT). Initial data were differences between mean frequency band coherence ~20 min after administration and values before administration (~30 min of baseline recording). For each group, 6–10 recordings were made.
Article Snippet: The training set, against which test-set pharmacological effects were classified, comprised previously published matrices of drug effects [ , , , , ]: the NMDA antagonist dizocilpine (Targetmol Chemicals Inc., Wellesley Hills, MA, USA); D2/D3 dopamine antagonists haloperidol (OOO Velpharm, Russia) and sulpiride (AO Organica, Novokuznetsk, Russia); the M-anticholinergic tropicamide (Tocris Bioscience, Bristol, UK); the H1/5-HT2A receptor blocker hydroxyzine (Sigma-Aldrich Chemie GmbH, Taufkirchen, Germany); the acetylcholinesterase inhibitor galantamine (Sopharma AD, Sofia, Bulgaria); the α2-adrenergic agonist dexmedetomidine (Orion Corporation, Espoo, Finland); and GABA-mimetics aminophenylbutyric acid (phenibut) (Tocris Bioscience, Bristol, UK) and bromdihydrochlorophenylbenzodiazepine (phenazepam) (AO Novosibkhimpharm, Novosibirsk, Russia) ( C).
