1 2 3 4 M 1 and M 4 receptors modulate hippocampal pyramidal neurons 5
31 Acetylcholine (ACh), acting at muscarinic ACh receptors (mAChRs), modulates the 32 excitability and synaptic connectivity of hippocampal pyramidal neurons. CA1 pyramidal 33 neurons respond to transient (" phasic ") mAChR activation with biphasic responses in 34 which inhibition is followed by excitation, whereas prolonged (" tonic ") mAChR activation 35 increases CA1 neuron excitability. Bot...
متن کاملStructures of [(CO2)n(CH3OH)m](-) (n = 1-4, m = 1, 2) cluster anions.
The infrared photodissociation spectra of [(CO 2) n (CH 3OH) m ] (-) ( n = 1-4, m = 1, 2) are measured in the 2700-3700 cm (-1) range. The observed spectra consist of an intense broad band characteristic of hydrogen-bonded OH stretching vibrations at approximately 3300 cm (-1) and congested vibrational bands around 2900 cm (-1). No photofragment signal is observed for [(CO 2) 1,2(CH 3OH) 1] (-)...
متن کاملStrongly Regular Graphs with Parameters ( 4 m 4 , 2 m 4 + m 2 , m 4 + m 2 , m 4 + m 2 ) Exist for
Using results on Hadamard difference sets, we construct regular graphical Hadamard matrices of negative type of order 4m for every positive integer m. If m > 1, such a Hadamard matrix is equivalent to a strongly regular graph with parameters (4m, 2m +m, m +m, m +m). Strongly regular graphs with these parameters have been called max energy graphs, because they have maximal energy (as defined by ...
متن کاملM/M/1 Feedback Queue Subject to Catastrophe and Repairment
In this paper, an M/M/1 queue with instantaneous Bernoulli feedback is studied in the event of server failure, the catastrophe occurs and after repair, it starts to work again. The transient response for the probability function of the system size is presented. The steady state analysis of system size probabilities and some performance measures of system are provided. Then the resu...
متن کامل1 Agency Theory
This note considers the simplest possible organization: one boss (or “Principal”) and one worker (or “Agent”). One of the earliest applications of this Principal-Agent model was to sharecropping, where the landowner was the Principal and the tenant farmer the Agent, but in this course we will typically talk about more familiar organization structures. For example, we might consider a firm’s sha...
