No association between ApoE polymorphism and febrile seizures

Lavenex, Pierre ; Lavenex, Pamela Banta ; Cachat, François ; Gehri, Mario ; Juvet, Typhaine

In: Neurological Sciences, 2015, p. 1–6

Seizures associated with fever are a common pediatric problem, affecting about 2–7 % of children between 3 months and 5 years of age. Differentiation of febrile seizures from acute symptomatic seizures secondary to central nervous system infections or seizures associated with fever in children with epilepsy is essential to provide appropriate treatment and follow-up care. Here, we tested the...

Human short-term spatial memory: Precision predicts capacity

Lavenex, Pamela Banta ; Boujon, , Valérie ; Ndarugendamwo, Angélique ; Lavenex, Pierre

In: Cognitive Psychology, 2015, vol. 77, p. 1–19

Here, we aimed to determine the capacity of human short-term memory for allocentric spatial information in a real-world setting. Young adults were tested on their ability to learn, on a trial-unique basis, and remember over a 1-min interval the location(s) of 1, 3, 5, or 7 illuminating pads, among 23 pads distributed in a 4 m × 4 m arena surrounded by curtains on three sides. Participants had to...

Development of allocentric spatial memory abilities in children from 18 months to 5 years of age

Ribordy, Farfalla ; Jabès, Adeline ; Banta Lavenex, Pamela A. ; Lavenex, Pierre

In: Cognitive Psychology, 2013, vol. 66, no. 1, p. 1–29

Episodic memories for autobiographical events that happen in unique spatiotemporal contexts are central to defining who we are. Yet, before 2 years of age, children are unable to form or store episodic memories for recall later in life, a phenomenon known as infantile amnesia. Here, we studied the development of allocentric spatial memory, a fundamental component of episodic memory, in two...

Spatial relational learning and memory abilities do not differ between men and women in a real-world, open-field environment

Banta Lavenex, Pamela A. ; Lavenex, Pierre

In: Behavioural Brain Research, 2010, vol. 207, no. 1, p. 125-137

This study assesses gender differences in spatial and non-spatial relational learning and memory in adult humans behaving freely in a real-world, open-field environment. In Experiment 1, we tested the use of proximal landmarks as conditional cues allowing subjects to predict the location of rewards hidden in one of two sets of three distinct locations. Subjects were tested in two different...
