Dynamical prefrontal population coding during defensive behaviours.

Coping with threatening situations requires both identifying stimuli that predict danger and selecting adaptive behavioural responses to survive. The dorsomedial prefrontal cortex (dmPFC) is a critical structure that is involved in the regulation of threat-related behaviour. However, it is unclear how threat-predicting stimuli and defensive behaviours are associated within prefrontal networks to successfully drive adaptive responses.

Assessing inter- and intraspecific variability of xylem vulnerability to embolism in oaks.

The genus comprises important species in forestry not only for their productive value but also for their ability to withstand drought. Hence an evaluation of inter- and intraspecific variation in drought tolerance is important for selecting the best adapted species and provenances for future afforestation. The presence of long vessels makes it difficult to assess xylem vulnerability to embolism in oak.
