Modulation of frequency preference in heterogeneous populations of theta-resonant neurons
(Pergamon-Elsevier, 2020)
Neurons from several brain regions resonate in the theta frequency range (4-12 Hz), displaying a higher voltage response to oscillatory currents at a preferred 'resonant' frequency (f(R)). Subthreshold resonance could ...
Frequency and Factors Associated with Sexual Response During Pregnancy
(2022)
Background: During pregnancy, the woman’s body undergoes deep biopsychosocial and hormonal
changes, which can lead to the appearance of complications and alterations in sexual response.
Objective: To determine the frequency ...
Basilar membrane mechanics at the base of the chinchilla cochlea. II. Responses to low-frequency tones and relationship to microphonics and spike initiation in the VIII Nervea)
(1986)
Low-frequency stimuli (40-to 1000-Hz tones) have been used to correlate the motion of the 8-to 9-kHz place of the chinchilla basilar membrane with the cochlear microphonics recorded at the round window and with the responses ...
Dependência da frequência dos parâmetros do solo: efeito no comportamento impulsivo de aterramentos elétricos
(Universidade Federal de Minas GeraisUFMG, 2013-07-30)
This PhD dissertation is dedicated to the study of the frequency dependence of soil electrical parameters and to the analysis of the impact of such phenomenon on the grounding response to transients, namely those associated ...
