Functional MRI is used pervasively in human brain research, enabling characterization of distributed brain activity underlying complex perceptual and cognitive processes. However, heretofore this technique has been limited in utility in rodents. I will present whole-brain functional imaging of head-fixed mice performing go/no-go odor discrimination in a platform allowing precise odor-delivery system, non-invasive sniff recordings and lick detection, detailing the brain regions subserving this behavior from the naïve state to task proficiency including learning of rule reversal. I will briefly discuss efforts to expand the mouse fMRI platform to additional modalities and conclude by describing the prospects of this approach more broadly.

Recent archaeological excavations at Manot Cave, an Early Upper Palaeolithic site in the Western Galilee, Israel, retrieved the remains of a partial left foot of a young adult, including the talus, the calcaneus, the cuboid and the first, second and fifth metatarsals. The pedal remains were found close to one another, in the same archaeological unit, and were associated with an Early Upper Palaeolithic assemblage.
Our study aimed at describing the anatomy of the Manot Cave pedal bones using morphometric parameters. A comparison to foot bones of recent modern humans, Anatomically Modern Humans and Neanderthals was carried out to establish the Manot Cave specimen population affiliation. Additionally, µCT images were used to verify a suspected injury in the base of the second metatarsal.
The shape and size of the Manot pedal bones indicated a modern morphology for all bones, albeit few Neanderthal-like characteristics. Imaging analysis confirmed the existence of a healed trauma in the second metatarsal, with the plantar third of the base misaligned with the shaft and a fracture line on the lateral side. These features are consistent with a fracture known as Lisfranc’s fracture, most probably caused by an impact to the dorsum of the foot. This injury usually leads to ligamentous instability and collapse of the transverse and longitudinal arches, causing severe walking difficulties. Full recovery requires rest and immobility for several weeks.
As mobility was crucial to maintain the hunter-gatherer lifeway of this group, the survival of this individual indicates a supportive community at Manot Cave.
