“…The few EEG N1 studies have observed a response between 2-6 months (Hammarrenger et al,2003;Morrone et al,1996;Taylor & McCulloch,1992). Whereas some EEG studies report no age-related P1 amplitude change in response to pattern reversal stimuli (Jiang et al,2023;Lenassi et al,2008), other studies report a gradual increase in P1 amplitude until ∼2 years old (Kos-Pietro et al,1997), and some a maximum P1 amplitude around 2-6 months of age (Crognale et al,1993; Hammarrenger et al,2003; Jensen et al,2019; Lippé et al,2007). The inconsistent P1 amplitude findings are likely due, in part, to the fact that some studies measure P1 amplitude as a baseline-to-peak measure (Hammarrenger et al,2003;Lippé et al,2007;Tremblay et al,2014) and some P1 amplitude from the peak of the previous N1 (Crognale et al,1993;Jensen et al,2019;Odom et al,2016).…”

Our understanding of how visual cortex neural processes mature during infancy and toddlerhood is limited. Using magnetoencephalography (MEG), the present study investigated the development of visual evoked responses (VERs) in both cross-sectional and longitudinal samples of infants and toddlers 2 months to 3 years. Brain space analyses focused on N1m and P1m latency, as well as the N1m-to-P1m amplitude. Associations between VER measures and developmental quotient (DQ) scores in the cognitive/visual and fine motor domains were also examined. Results showed a nonlinear decrease in N1m and P1m latency as a function of age, characterized by rapid changes followed by slower progression, with the N1m latency plateauing at 6-7 months and the P1m latency plateauing at 8-9 months. The N1m-to-P1m amplitude also exhibited a non-linear decrease, with strong responses observed in younger infants (∼2-3 months) and then a gradual decline. Associations between N1m and P1m latency and fine motor DQ scores were observed, suggesting that infants with faster visual processing may be better equipped to perform fine motor tasks. The present findings advance our understanding of the maturation of the infant visual system and highlight the relationship between the maturation of visual system and fine motor skills.HighlightsThe infant N1m and P1m latency shows a nonlinear decrease.N1m latency decreases precede P1m latency decreases.N1m-to-P1m amplitude shows a nonlinear decrease, with stronger responses in younger than older infants.N1m and P1m latency are associated with fine motor DQ.

“…8 The different components of VEP are disturbed in different disorders for example latency of VEP is prolonged in demyelinating diseases of the visual pathway and the amplitude is reduced in the axonal damage. 9,10 The rationale of study is to prevent the misinterpretation of the VEP results for ocular pathologies in the more prevalent myopia individuals. Present study determine effects of myopia on Visual Evoked Potentials in subjects attending tertiary care eye hospital.…”

bjective: To determine the effects of myopia on Visual Evoked Potentials among the subjects attending the eye OPD.Study design and setting: This was a cross-sectional study with non-probability convenience sampling technique carriedout at Department of Ophthalmology, Peoples Medical College Hospital Nawabshah / GMMMC Sukkur from March 2021to November 2021.Methodology: Total sample size was derived to be 180. Diagnosed myopia irrespective of gender and aged 25 to 45 yearswere included. Optic atrophy, Extensive retinal disease, any neurological disorder like multiple sclerosis, stroke and Visualpathway disorders were excluded. SPSS version 25.0 was used for data analysis.Results: The mean age of the patients was 39.14 ± 6.73 years. There were n=96 (53%) females and n=84 (47%) males.In myopic samples the mean pattern stimuli latency P100 in right eye was 92.07 ±5.1 in cases (without correction) and82.09 ± 5.8 in controls (with correction) with significant P-value 0.023, while in left eye was 93.55 ± 6.7 in cases (withoutcorrection) and 83.6 ± 7.0 in controls (with correction) with significant P-value 0.028.Conclusion: Greater the myopia; greater was the Visual Evoked Potential (VEP) changes with regards to latency andamplitude in pattern stimuli especially P100 being the most affected component in this regard. It is therefore necessarythat every patient who goes for VEP test should be corrected for myopic refractive error.
