6.1 Firing-rate hypothesis

Information about stimulus intensity is encoded in two ways: the firing rates of neurons and the number of active neurons.

Intensity is assumed to be encoded by an increase in discharge rate of action potentials within the auditory system. As the stimulus gets more intense, the basilar membrane vibrates at a greater amplitude causing the membrane potential of activated hair cells to be more depolarised and this causes the nerve fibres that synapse onto the hair cells to fire at a greate

Waste Management
How much do you think about what you throw away? A waste management cycle is essential for a sustainable future.

1.3.3 The role of clouds

We have already identified one role that clouds play in the Earth's climate: they are highly reflective (Section 1.2.1). At any given time, about half of our planet is covered by clouds; the sunlight they reflect back to space accounts for about 55% of the total planetary albedo. However, clouds also absorb and re-emit outgoing longwave radiatio

5.2 Blair's babe

The ESRC report demonstrated the high awareness amongst the public of the Leo Blair issue, in spite of it not being the most prominent aspect of the media coverage. In December 2001, during Prime Minister's Questions in the House of Commons, Tony Blair was asked whether his infant son had been immunised with MMR. Mr Blair declined to answer on the basis that it was a private family matter. The perception in the media was that if Leo had been immunised, Mr Blair would have been happy to say so

biosights: September 1, 2014 - Deploying exosomes in a battle of the sexes
By: JCB The paired accessory glands of male Drosophila secrete multiple signaling factors into the seminal fluid that promote reproductive success by altering the recipient female's physiology and behavior. Corrigan et al. reveal that the secondary cells of accessory glands secrete membrane-bound exosomes in a BMP-dependent manner that, after being transferred into the female reproductive tract, inhibit the female's inclination to re-mate with other male flies.

1 Springs

We have seen that where precipitation reaches the ground, some runs off the surface into streams and rivers and some of it infiltrates, passing through the soil. Water that reaches the water table to become groundwater may eventually re-emerge at the surface as springs where the water table intersects the surface. Almost all streams and rivers have springs or seepages as their ultimate source, or are fed by them at various points along their courses.
