We used the Gemini Multi-Object Spectrograph Integral Field Unit to map thegas distribution, excitation and kinematics within the inner kiloparsec of fournearby low-luminosity active galaxies: NGC3982, NGC4501, NGC2787 and NGC4450.The observations cover the spectral range 5600-7000{\AA} at a velocityresolution of 120km/s and spatial resolution ranging from 50 to 70pc at thegalaxies. Extended emission in H{\alpha}, [NII]{\lambda}{\lambda}6548,6583,[SII]{\lambda}{\lambda}6716,6730 over most of the field-of-view is observed forall galaxies, while only NGC3982 shows [OI]{\lambda}6300 extended emission. TheH{\alpha} equivalent widths combined with the [NII]/H{\alpha} line ratiosreveal that NGC3982 and NGC4450 harbor Seyfert nuclei surrounded by regionswith LINER excitation, while NGC2787 and NGC4501 harbor LINER nuclei. NGC3982shows a partial ring of recent star-formation at 500pc from the nucleus, whilein NGC4501 a region at 500pc west of the nucleus shows LINER excitation but hasbeen interpreted as an aging HII region with the gas excitation dominated byshocks from supernovae. The line-of-sight velocity field of the gas shows arotation pattern for all galaxies, with deviations from pure disk rotationobserved in NGC3982, NGC4501 and NGC4450. For NGC4501 and NGC4450, many ofthese deviations are spatially coincident with dust structures seen in opticalcontinuum images, leading to the interpretation that the deviations are due toshocks in the gas traced by the dust. A speculation is that these shocks leadto loss of angular momentum, allowing the gas to be transferred inwards to feedthe AGN. In the case of NGC2787, instead of deviations in the rotation field,we see a misalignment of 40{^\circ} between the orientation of the line ofnodes of the gas rotation and the photometric major axis of the galaxy.Evidence of compact nuclear outflows are seen in NGC4501 and NGC4450.
