A controlled, quantitative investigation of the electroencephalogram (EEG) and transcendental meditation (TM) revealed that EEG changes during TM were rarely as pronounced or consistent as previous
Reflex response changes of the toad spinal cord to variations in temperature and pH.
TLDR
Temperature increases depolarized and decreases hyperpolarized dorsal root terminals and increases in the H+ concentration caused a depolarization with a simultaneous decrease in amplitude and increase in duration of the VRR, dorsal and ventral root potentials.
A re-evaluation of the mode of action of 5-hydroxytryptamine on lateral geniculate neurones: Comparison with catecholamines and LSD
TLDR
It is concluded that the tryptamine derivatives and LSD in low concentrations either block the release of the excitatory transmitter from optic nerve terminals, or block its access to receptors on LGN neurones.
Actions of amino acids and convulsants on bulbar reticular neurones
TLDR
A comparison of the results with those obtained in the spinal cord provides some evidence that glycine may be an inhibitory transmitter substance released on bulbar reticular neurones.
The pharmacology of acetylcholine-excitation of thalamic neurones.
Strychnine-sensitive inhibition in the medullary reticular formation: evidence for glycine as an inhibitory transmitter.
TLDR
Evidence was obtained that glycine is an inhibitory transmitter in the medullary reticular formation and was a more effective depressant than GABA of all the reticular neurones identified by antidromic stimulation.
Histamine and some antihistamines: their actions on cerebral cortical neurones.
The use of convulsants in studying possible functions of amino acids in the toad spinal cord.
TLDR
Picrotoxin reduced the depolarizing effects of l -glutamic acid and GABA on dorsal roots, and depressed dorsal root reflexes, and strychnine blocked the hyperpolarized effects of β-alanine and glycine, but not of GABA, on ventral roots.
Depression of spinal motoneurones by noradrenaline, 5-hydroxytryptamine and histamine.
TLDR
All three monoamines applied extracellularly to spinal neurones caused an increase in membrane polarization, a decrease in amplitude of EPSPs and IPSPs and blocked the synaptic or antidromic invasion of some neurones, compatible with those of an inhibitory transmitter.
