Biological psychologists (sometimes referred to as neuropsy-chologists) attempt to understand how the neural circuits and connections are formed and put together during the development of the brain, allowing the individual to perceive and interact with the world around them.

May 26, 2021 · Neuromodulators trigger second messenger cascades that affect neural circuits in two broad ways: (1) changing the excitability or temporal pattern of neuron activity and (2) altering the strength of synaptic connections between neurons (Marder and Bucher 2001; Dickinson 2006).

What is neuromodulator? Neurotransmitters. 90% 9% Amino acids (Glutamate, GABA, Glycine, etc) Gas (NO, CO, H2S)
Dec 1, 2014 · The divergent and convergent neuromodulator actions can be unambiguously synergistic or antagonistic, but neuromodulation often entails balanced adjustment of nonlinear membrane and synaptic properties by targeting ion channel and synaptic dynamics rather than just excitability or synaptic strength.
- The subsystems involved in bacterial chemotaxis (from Egbert et al. 2010) Full size image. Indeed, the classical model of chemotaxis (see Eisenbach 2004; Wadhams and Armitage 2004) describes the functioning of the whole mechanism of control of movement as operationally independent from metabolism, even if metabolism must provide the energy for movement and ensure the synthesis and maintenance of the components of the subsystems involved.
- Schematic representation of Deamer’s idea of a basic feedback loop operating in vesicles during an early stage of origins of life. Those vesicles that manage to synthesize oligopeptides, whose assembly at the membrane interface can increase the permeability to nutrients (X, Y and Z in the graph), would reinforce their metabolism (thickened internal cycle of reactions).
- Scheme of Gánti’s chemoton with the three coupled cycles: a metabolic cycle, a template replication cycle and a compartment (Moreno and Mossio 2015: 26.
- Feedback inhibition of an enzyme E by a product metabolite N. Full size image. These features make allosteric feedback inhibition a borderline case, because it is a rather sophisticated dynamic stability mechanism.
Aug 1, 2000 · A complete answer to this question requires identification of the neural circuits responsible, the different neural components involved, their connectivity, transmitters, the types of channels they possess, and their modulation via various receptors.
