Intracellular recordings were obtained from neurons of the laterodorsal tegmental and pedunculopontine tegmental nuclei in a brain-slice preparation. The action of exogenously applied 5-hydroxytryptamine and acetylcholine was studied on NADPH-diaphorase-labeled cells which contain nitric oxide synthase and are presumed to be cholinergic. Our results indicated that these cells were hyperpolarized by both 5-hydroxytryptamine and acetylcholine; the ionic mechanism of this inhibition was investigated using current and voltage clamp methods. Cells voltage-clamped at resting membrane potential exhibited a net outward current and an increased membrane conductance during 5-hydroxytryptamine and acetylcholine mediated inhibition. The membrane hyperpolarization and outward current generated by this paradigm reversed near the expected K equilibrium potential and was blocked by low concentrations of extracellular Ba. The 5-hydroxytryptamine- and acetylcholine-dependent currents showed inward rectification and the reversal potential shifted in the depolarizing direction by about 15 mV for a doubling of extracellular K, indicating that both 5-hydroxytryptamine and acetylcholine activate inwardly rectifying, potassium-selective conductances. The outward currents evoked by 5-hydroxytryptamine and acetylcholine were not additive, suggesting that both receptors are coupled to an overlapping pool of K channels as has been observed in several systems in which receptors are coupled to effectors by G-proteins.

These results indicate that the dominant actions of 5-hydroxytryptamine and acetylcholine relate to the inhibition of mesopontine cholinergic neurons via activation of an overlapping pool of inwardly rectifying K channels. YU-card provides access to several services and spaces across Keele, Glendon and Markham campuses including the library, recreation facilities, exams, food, dining plans, shopping, events, discounts and more.

The action of exogenously applied 5-hydroxytryptamine and acetylcholine was studied on NADPH-diaphorase-labeled cells which contain nitric oxide synthase and are presumed to be cholinergic. Abstract Intracellular recordings were obtained from neurons of the laterodorsal tegmental and pedunculopontine tegmental nuclei in a brain-slice preparation. Our results indicated that these cells were hyperpolarized by both 5-hydroxytryptamine and acetylcholine; the ionic mechanism of this inhibition was investigated using current and voltage clamp methods. Accordingly, models of the neural substrate underlying rapid eye movement sleep production need to be changed to reflect this inhibitory action of acetylcholine on cholinergic neurons. Select the appropriate session from the drop-down menu. A course with a 3. Be sure to leave yourself enough time to enrol in classes. The outward currents evoked by 5-hydroxytryptamine and acetylcholine were not additive, suggesting that both receptors are coupled to an overlapping pool of K channels as has been observed in several systems in which receptors are coupled to effectors by G-proteins. Intracellular recordings were obtained from neurons of the laterodorsal tegmental and pedunculopontine tegmental nuclei in a brain-slice preparation.

Continuing undergraduate students are assigned a time and date to access the registration and enrolment module REM. Continuing students should schedule an academic advising appointment before enrolling to ensure they are picking the right courses. After their advising appointment and once access is granted, students should enrol immediately.

YU-card provides access to several services and spaces across Keele, Glendon and Markham campuses including the library, recreation facilities, exams, food, dining plans, shopping, events, discounts and more. Your Student Account Once you have enrolled in a course, you must pay the registration deposit to reserve your place in it. You will need your York student number, provided to you in your admission letter, to continue. The credit value normally correlates to the length of the course and the number of hours the course meets per week. Connect with the Division of Students. The 5-hydroxytryptamine- and acetylcholine-dependent currents showed inward rectification and the reversal potential shifted in the depolarizing direction by about 15 mV for a doubling of extracellular K, indicating that both 5-hydroxytryptamine and acetylcholine activate inwardly rectifying, potassium-selective conductances.

Please note: It could take up to 48 hours to activate a Passport York account during busy times. You can now proceed to enrol in courses. It has been previously hypothesized that acetylcholine would be excitatory and that 5-hydroxytryptamine would be inhibitory to these cells in the context of rapid eye movement sleep. The preferred method of payment is through the Internet or telephone banking. We encourage you to enrol as early as possible and to identify alternate course choices. Intracellular recordings were obtained from neurons of the laterodorsal tegmental and pedunculopontine tegmental nuclei in a brain-slice preparation. Parking Services at York functions on both daily rates and monthly or sessional parking passes. These results indicate that the dominant actions of 5-hydroxytryptamine and acetylcholine relate to the inhibition of mesopontine cholinergic neurons via activation of an overlapping pool of inwardly rectifying K channels.
