Short-term plasticity has a long synaptic history

Short- and long-term synaptic plasticity are dynamically linked, and this interplay helps to increase the information storage capacity of a synapse reports Yuji Ikegaya

  • Features

Melatonin, sleep and the biological clock

Jo Arendt cuts through the hype and looks at the genuine benefits of a ‘hormone of darkness’

Physiology in the extreme: The case for microgravity research

Why should UK life scientists be excluded from the opportunity of using space agencies’ resources to study problems of major physiological and clinical interest?

  • Features

The effects of spike activity on measures of neural encoding

Single neurones are driven to fire at precise times by certain features in their input. We have recently shown that the spike-triggering features reflect the influence of both the stimulus and previous spikes on firing probability

Hepcidin, body iron and infection
  • Features

Glycolysis has many ways to regulate cardiac function

Interplay between neutrophils and skeletal muscle after exercise. What’s going on?

Neutrophils appear in skeletal muscle after exercise. The mechanisms by which skeletal muscle activates neutrophils and the function of neutrophils in skeletal muscle are, write Francis Pizza and colleagues, beginning to be revealed

Integrity and vulnerability of skeletal muscle innervation in ageing mammals

Skeletal muscle weakness in ageing mammals may result from factors affecting the neural control of muscle structure and function. Muscle denervation is relentless and a more extensive process than previously believed. Partially denervated muscle cells, recently described in senescent mice, might contribute to muscle weakness in ageing mammals

The tongue does not the taste system make

The taste system responds to diverse chemical stimuli that affect not only taste receptors on the tongue, but also taste receptors on the palate. Despite the highly complex nature of taste stimuli and the many sites of receptor activation, the brain appears to code the tastes of food and fluid in a relatively stable manner
