Mean temporal patterns of gross locomotor activity.

<p>Average and standard error (SEM) of the diurnal profile of activity in intact rabbit pups (INT), intact pups fed by enteral gavage (INT+ENT), sham operated pups (SHAM), pups with unilateral lesions of the olfactory bulb (OBx-UNI) and pups with bilateral lesions of the olfactory bulb (OBx-BI). From postnatal day (P) 6–8, the pups were nursed or fed artificially every 24 h at 11:00 (indicated by the vertical red bar), from postnatal day 9–13 the feeding schedule was delayed 6 h (17:00), and from P14-15 the pups were maintained under fasting conditions. The red dotted line indicates the daily mean activity.</p

Temporal patterns of gross locomotor activity.

<p>Representative daily profiles of activity in newborn rabbits as measured using biotelemetry, in intact pups (INT), intact pups fed by enteral gavage (INT+ENT), sham operated pups (SHAM), pups with unilateral lesions of the olfactory bulb (OBx-UNI) and pups with bilateral lesions of the olfactory bulb (OBx-BI). From postnatal day 6–8, the pups were nursed or fed artificially every 24 h at 11:00 (indicated by the vertical red bar), from postnatal day 9–13 the feeding schedule was delayed 6 h (17:00), and from P14-15 the pups were maintained under fasting conditions (see text for details). The red dotted line indicates the daily mean activity.</p

Daily phases of gross locomotor activity.

<p>The daily acrophases (black triangles) and nadirs (gray triangles) of the diurnal pattern of gross locomotor activity in intact rabbit pups (INT), intact pups fed by enteral gavage (INT+ENT), sham operated pups (SHAM), pups with unilateral lesions of the olfactory bulb (OBx-UNI) and pups with bilateral lesions of the olfactory bulb (OBx-BI). From postnatal day 6–8, the pups were nursed or fed artificially every 24 h at 11:00 (indicated by the vertical red bar), from postnatal day 9–13 the feeding schedule was delayed 6 h (17:00), and from P14-15 the pups were maintained under fasting conditions. The black line indicates one half of the cycle. Mean ± SEM.</p

Temporal patterns of core body temperature.

<p>Representative daily profiles of temperature as measured using biotelemetry in newborn intact rabbit pups (INT), intact pups fed by enteral gavage (INT+ENT), sham operated pups (SHAM), pups with unilateral lesions of the olfactory bulb (OBx-UNI) and pups with bilateral lesions of the olfactory bulb (OBx-BI). From postnatal day 6–8, the pups were nursed or fed artificially every 24 h at 11:00 (indicated by the vertical red bar), from postnatal day 9–13 the feeding schedule was delayed 6 h (17:00), and from P14-15 the pups were maintained under fasting conditions (see text for details). The dotted red line indicates the daily mean temperature.</p

Daily average gross locomotor activity.

<p>The mean activity from postnatal day 6–15 of intact rabbit pups (INT, dark blue circles), intact pups fed by enteral gavage (INT+ENT, dark cyan hexagons), sham operated pups (SHAM, dark green triangles), pups with lesions of the olfactory bulb (OBx-UNI, dark red diamonds), and pups with bilateral lesions of the olfactory bulb (OBx-BI, red squares).
