I understand that the relay of sensory information would be disrupted, but how would this manifest itself?

Depends on the location and extension of the injury. Thalamic amnesia: Left sided lesions produce verbal memory deficit, right sided lesions produce visual memory impairment. Bilateral lesions a permanent disabling global amnesia or thalamic dementia.
Mild fronto-limbic behavioral changes are also observed. Mammillothalamic tract--------anterior thalamic nucleus (Papez circuit)
Amygdala and perirhinal cortex (ventral amygdalofugal)------dorsomedial thalamic nuclei-------prefrontal cortex

I agree with forge. In practice we see three set of patients with such lesion. Majority with no permanent damage. Some with sensory deficit more like hypersensitiviy problems. Some with more complex problems like with memory, but those are rarely isolated thalamic lesions.

It is a low rooted part of the brain... near the stem...
I'll ask my wife when she gets home, but I believe it mainly regulates a persons moods..
