- Effects of environmental enrichment on forebrain neural plasticity and survival success of stocked Atlantic salmon
Summary: Structural enrichment increases the survival success of hatchery salmon in the wild.
- Portia’s capacity to decide whether a detour is necessary
Summary: A spider-eating predator, Portia africana, plans ahead of time whether to access its prey by taking a detour or a direct route.
- Hornets possess long-lasting olfactory memories
Summary: Hornet queens, drones and workers have excellent olfactory learning that can persist for up to 30 days in queens and drones.
- Plastic changes in brain morphology in relation to learning and environmental enrichment in the guppy (Poecilia reticulata)
Summary: Modifications of the brain can occur as a form of adaptation to environmental conditions. Environmental enrichment was found to influence relative brain size in guppies.
- Spontaneous alternation behavior in larval zebrafish
Summary: Larval zebrafish show spontaneous alternation behavior, supporting the future use of zebrafish as a high-throughput pharmacological model in mnestic studies.
- Spatial learning in the cuttlefish Sepia officinalis: preference for vertical over horizontal information
Summary: Vertical and horizontal information is separated in a marine invertebrate, the common cuttlefish, with priority given to vertical information.
- Scaling of cerebral blood perfusion in primates and marsupials
Summary: Brain blood flow rate increases with brain size and body size much faster in primates than in marsupial mammals, correlating with differences in cognitive ability.
