This table shows the classification of those cells that were identified as related to the transport or lever press phase during the contralateral reach when the animals performed an ipsilateral reach. For those cells showing multiple periods of activity, we initially determined whether significant changes occurred in a given phase in the two conditions. For example, for a cell that showed a dynamic increase during contralateral reach, we first verified whether it had a similar period of activity during ipsilateral reach. In the absence of a match, we note at which phase the cells did change their activity. Asterisks indicate that the cell discharged tonically, discharging during the lever press phase, and continuing subsequent to this; values without asterisks indicate dynamic changes. Values in bold indicate periods of activity that occur in the same phase in both contralateral and ipsilateral reach (These have identical values in Table 5.). Note that data during the ipsilateral reach were recorded between two blocks of contralateral reaches (see above, Materials and Methods). mod, modulated.
