Transient pattern visual evoked potentials in children with Down's syndrome.
Suttle CM, Turner AM. Suttle CM, et al. Ophthalmic Physiol Opt. 2004 Mar;24(2):91-9. doi: 10.1046/j.1475-1313.2003.00174.x. Ophthalmic Physiol Opt. 2004. PMID: 15005673
However, abnormal spatial vision persists in children with Down's syndrome in the absence of ocular abnormality, suggesting that abnormal retino-cortical visual processing explains reduced visual function in this group. The aim of the present study was to assess ret …

Human sensory-evoked responses differ coincident with either "fusion-memory" or "flash-memory", as shown by stimulus repetition-rate effects.
Jewett DL, Hart T, Larson-Prior LJ, Baird B, Olson M, Trumpis M, Makayed K, Bavafa P. Jewett DL, et al. BMC Neurosci. 2006 Feb 23;7:18. doi: 10.1186/1471-2202-7-18. BMC Neurosci. 2006. PMID: 16504094 Free PMC article.
BACKGROUND: A new method has been used to obtain human sensory evoked-responses whose time-domain waveforms have been undetectable by previous methods. These newly discovered evoked-responses have durations that exceed the time between the stimuli in a contin …
