One strategy to use and expand upon the abilities of living systems to detect substances is to computationally re-design biological receptors that
mediate responses to external stimuli.
Due to the crucial role of G protein - coupled receptors (GPCRs) in mediating
cellular responses to external stimuli, these receptors have been and will remain a prime focus for medical research and the pharmaceutical industry for many years to come.
With it, they want to determine the firing patterns of specific neuron groupings in
response to external stimuli which, in turn, will be used to «elicit sensory percepts in the visual or somatosensory cortices.»
During his postdoc, Barboiu entered the field of molecular machines, molecular assemblies able to perform mechanical movements
in response to external stimuli.
Depending on different parameters, such as the particle / wall charge and the extension of the charged regions on the particle surface, our units can form surface layers with different densities (and possibly
different responses to external stimuli): sometimes particles assemble into close - packed, hexagonally ordered crystalline aggregates, sometimes they form open, square - like layers, sometimes they do not assemble at all.
And producing a word is even more difficult because the excitatory impulse isn't
a response to an external stimulus — it needs to come from within.
The brain, Damasio says, learns from the body's
response to external stimuli, but the brain is also a master simulator, capable of building mock versions of that emotional reaction.
Depending on the microscopic alignment of the particles, they create surface types with different densities and different
responses to external stimuli (e.g. elcetromagnetic fields).
The research focused on a compound called neuroprotectin D1 = protectin D1 (NPD1 = PD1), a bioactive lipid produced by cells in
response to external stimuli.
To see whether roosters simply crow in
response to external stimuli or according to a circadian rhythm — an internally driven, cyclical pattern of behavior that occurs over a 24 - hour period — the team put one group of birds into a room with continuously dim lights and tracked the birds» crowing over the course of a month.
Nagoya, Japan — Stimuli - responsive materials alter their own properties in
response to external stimuli, such as photo - irradiation, heat, pressure and electricity.
The aim of this project is to explore whether the genome three - dimensional (3D) structure acts as an information store that modulates transcription in
response to external stimuli.
This is of interest because a cell's genetic material is housed in the nucleus, and this is the location where different genes get turned on and off in
response to external stimuli, such as the presence of lipids from fatty foods.
Thus, the endocrine system is crucial for our survival and health, and, because many crucial hormones are secreted in the brain, and our brain activity and
response to external stimuli can affect hormone release, your mind and your environment are very important to the health of the individual at large.
While stress often occurs in
response to an external stimulus (like an argument with your spouse), anxiety tends to be more of an internal state.
Its conceptual departure point is the male cremaster muscle, which controls testicular contractions in
response to external stimuli.
