Cells and tissues can vary in competence, their ability to respond to external signals.

Other sources of noise may include external electrical signals or poorly designed components.

PGC-1α is thought to be a master integrator of external signals.

The smaller room beyond, in contrast to the one where Milly stood, was completely shielded from external signals.

It is negatively correlated with brain systems that focus on external visual signals.

Among other changes, this standard introduces the use of external signals.

No external signals are needed to initiate this process.

Cancer cells do not need stimulation from external signals (in the form of growth factors) to multiply.

It is important to identify only the external tactile signals for accurate operations.

All these external signals feed into the "speech production system" through the auditory cortex.
